    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.5 Extended Update Support. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-8159, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file (/dev/fb*) could possibly use this flaw to escalate their privileges on the system. (CVE-2013-2596, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel's ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) Red Hat would like to thank Mellanox for reporting CVE-2014-8159, and Andy Lutomirski for reporting CVE-2014-3690. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * Previously, a NULL pointer check that is needed to prevent an oops in the nfs_async_inode_return_delegation() function was removed. As a consequence, a NFS4 client could terminate unexpectedly. The missing NULL pointer check has been added back, and NFS4 client no longer crashes in this situation. (BZ#1187638) * Due to unbalanced multicast join and leave processing, the attempt to leave a multicast group that had not previously completed a join became unresponsive. This update resolves multiple locking issues in the IPoIB multicast code that allowed multicast groups to be left before the joining was entirely completed. Now, multicast join and leave failures or lockups no longer occur in the described situation. (BZ#1187663) * A failure to leave a multicast group which had previously been joined prevented the attempt to unregister from the 'sa' service. Multiple locking issues in the IPoIB multicast join and leave processing have been fixed so that leaving a group that has completed its join process is successful. As a result, attempts to unregister from the 'sa' service no longer lock up due to leaked resources. (BZ#1187665) * Due to a regression, when large reads which partially extended beyond the end of the underlying device were done, the raw driver returned the EIO error code instead of returning a short read covering the valid part of the device. The underlying source code has been patched, and the raw driver now returns a short read for the remainder of the device. (BZ#1195746) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * In certain systems with multiple CPUs, when a crash was triggered on one CPU with an interrupt handler and this CPU sent Non-Maskable Interrupt (NMI) to another CPU, and, at the same time, ioapic_lock had already been acquired, a deadlock occurred in ioapic_lock. As a consequence, the kdump service could become unresponsive. This bug has been fixed and kdump now works as expected. (BZ#1197742) * On Lenovo X1 Carbon 3rd Gen, X250, and T550 laptops, the thinkpad_acpi module was not properly loaded, and thus the function keys and radio switches did not work. This update applies a new string pattern of BIOS version, which fixes this bug, and function keys and radio switches now work as intended. (BZ#1197743) * During a heavy file system load involving many worker threads, all worker threads in the pool became blocked on a resource, and no manager thread existed to create more workers. As a consequence, the running processes became unresponsive. With this update, the logic around manager creation has been changed to assure that the last worker thread becomes a manager thread and does not start executing work items. Now, a manager thread exists, spawns new workers as needed, and processes no longer hang. (BZ#1197744) * If a thin-pool's metadata enters read-only or fail mode, for example, due to thin-pool running out of metadata or data space, any attempt to make metadata changes such as creating a thin device or snapshot thin device should error out cleanly. However, previously, the kernel code returned verbose and alarming error messages to the user. With this update, due to early trapping of attempt to make metadata changes, informative errors are displayed, no longer unnecessarily alarming the user. (BZ#1197745) * When running Red Hat Enterprise Linux as a guest on Microsoft Hyper-V hypervisor, the storvsc module did not return the correct error code for the upper level Small Computer System Interface (SCSI) subsystem. As a consequence, a SCSI command failed and storvsc did not handle such a failure properly under some conditions, for example, when RAID devices were created on top of storvsc devices. An upstream patch has been applied to fix this bug, and storvsc now returns the correct error code in the described situation. (BZ#1197749) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description This update fixes the CVEs described below. A further issue, CVE-2014-9419, was considered, but appears to require extensive changes with a consequent high risk of regression. It is now unlikely to be fixed in squeeze-lts. CVE-2013-6885 It was discovered that under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on AMD 16h 00h through 0Fh processors. A local user can use this flaw to mount a denial of service (system hang) via a crafted application. For more information please refer to the AMD CPU erratum 793 in http://support.amd.com/TechDocs/51810_16h_00h-0Fh_Rev_Guide. pdf CVE-2014-7822 It was found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects. CVE-2014-8133 It was found that the espfix functionality can be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks for) and using it for stack. A local unprivileged user could potentially use this flaw to leak kernel stack addresses. CVE-2014-8134 It was found that the espfix functionality is wrongly disabled in a 32-bit KVM guest. A local unprivileged user could potentially use this flaw to leak kernel stack addresses. CVE-2014-8160 It was found that a netfilter (iptables or ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol. CVE-2014-9420 It was found that the ISO-9660 filesystem implementation (isofs) follows arbitrarily long chains, including loops, of Continuation Entries (CEs). This allows local users to mount a denial of service via a crafted disc image. CVE-2014-9584 It was found that the ISO-9660 filesystem implementation (isofs) does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted disc image. CVE-2014-9585 It was discovered that address randomisation for the vDSO in 64-bit processes is extremely biassed. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. CVE-2015-1421 It was found that the SCTP implementation could free authentication state while it was still in use, resulting in heap corruption. This could allow remote users to cause a denial of service or privilege escalation. CVE-2015-1593 It was found that address randomisation for the initial stack in 64-bit processes was limited to 20 rather than 22 bits of entropy. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The following security bugs were fixed : - CVE-2015-5707: An integer overflow in the SCSI generic driver could be potentially used by local attackers to crash the kernel or execute code. - CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel did not prevent the TS_COMPAT flag from reaching a user-mode task, which might have allowed local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16 (bnc#926240). - CVE-2015-0777: drivers/xen/usbback/usbback.c in the Linux kernel allowed guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors (bnc#917830). - CVE-2015-2150: Xen and the Linux kernel did not properly restrict access to PCI command registers, which might have allowed local guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response (bnc#919463). - CVE-2015-5364: A remote denial of service (hang) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-5366: A remote denial of service (unexpected error returns) via UDP flood with incorrect package checksums was fixed. (bsc#936831). - CVE-2015-1420: CVE-2015-1420: Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel allowed local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function (bnc#915517). - CVE-2015-4700: A local user could have created a bad instruction in the JIT processed BPF code, leading to a kernel crash (bnc#935705). - CVE-2015-1805: The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel did not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allowed local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an 'I/O vector array overrun' (bnc#933429). - CVE-2015-3331: The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel did not properly determine the memory locations used for encrypted data, which allowed context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket (bnc#927257). - CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel allowed remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message (bnc#922583). - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel used an incorrect data type in a sysctl table, which allowed local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry (bnc#919007). - CVE-2015-3636: The ping_unhash function in net/ipv4/ping.c in the Linux kernel did not initialize a certain list data structure during an unhash operation, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect (bnc#929525). - CVE-2014-8086: Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel allowed local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag (bnc#900881). - CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel did not properly restrict use of User Verbs for registration of memory regions, which allowed local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/ (bnc#914742). - CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename (bnc#918333). - CVE-2015-2042: net/rds/sysctl.c in the Linux kernel used an incorrect data type in a sysctl table, which allowed local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry (bnc#919018). - CVE-2015-1421: Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel allowed remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data (bnc#915577). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description From Red Hat Security Advisory 2015:0864 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes several bugs. Documentation for these changes is available from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leaks or privilege escalation. - CVE-2013-7421 / CVE-2014-9644 It was discovered that the Crypto API allowed unprivileged users to load arbitrary kernel modules. A local user can use this flaw to exploit vulnerabilities in modules that would not normally be loaded. - CVE-2014-7822 Akira Fujita found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects. - CVE-2014-8160 Florian Westphal discovered that a netfilter (iptables/ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol. - CVE-2014-8559 It was found that kernel functions that iterate over a directory tree can dead-lock or live-lock in case some of the directory entries were recently deleted or dropped from the cache. A local unprivileged user can use this flaw for denial of service. - CVE-2014-9585 Andy Lutomirski discovered that address randomisation for the vDSO in 64-bit processes is extremely biased. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. - CVE-2014-9683 Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service. - CVE-2015-0239 It was found that KVM did not correctly emulate the x86 SYSENTER instruction. An unprivileged user within a guest system that has not enabled SYSENTER, for example because the emulated CPU vendor is AMD, could potentially use this flaw to cause a denial of service or privilege escalation in that guest. - CVE-2015-1420 It was discovered that the open_by_handle_at() system call reads the handle size from user memory a second time after validating it. A local user with the CAP_DAC_READ_SEARCH capability could use this flaw for privilege escalation. - CVE-2015-1421 It was found that the SCTP implementation could free an authentication state while it was still in use, resulting in heap corruption. This could allow remote users to cause a denial of service or privilege escalation. - CVE-2015-1593 It was found that address randomisation for the initial stack in 64-bit processes was limited to 20 rather than 22 bits of entropy. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism.

Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-8159, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * In certain systems with multiple CPUs, when a crash was triggered on one CPU with an interrupt handler and this CPU sent Non-Maskable Interrupt (NMI) to another CPU, and, at the same time, ioapic_lock had already been acquired, a deadlock occurred in ioapic_lock. As a consequence, the kdump service could become unresponsive. This bug has been fixed and kdump now works as expected. (BZ#1197742) * On Lenovo X1 Carbon 3rd Gen, X250, and T550 laptops, the thinkpad_acpi module was not properly loaded, and thus the function keys and radio switches did not work. This update applies a new string pattern of BIOS version, which fixes this bug, and function keys and radio switches now work as intended. (BZ#1197743) * During a heavy file system load involving many worker threads, all worker threads in the pool became blocked on a resource, and no manager thread existed to create more workers. As a consequence, the running processes became unresponsive. With this update, the logic around manager creation has been changed to assure that the last worker thread becomes a manager thread and does not start executing work items. Now, a manager thread exists, spawns new workers as needed, and processes no longer hang. (BZ#1197744) * If a thin-pool's metadata enters read-only or fail mode, for example, due to thin-pool running out of metadata or data space, any attempt to make metadata changes such as creating a thin device or snapshot thin device should error out cleanly. However, previously, the kernel code returned verbose and alarming error messages to the user. With this update, due to early trapping of attempt to make metadata changes, informative errors are displayed, no longer unnecessarily alarming the user. (BZ#1197745) * When running Red Hat Enterprise Linux as a guest on Microsoft Hyper-V hypervisor, the storvsc module did not return the correct error code for the upper level Small Computer System Interface (SCSI) subsystem. As a consequence, a SCSI command failed and storvsc did not handle such a failure properly under some conditions, for example, when RAID devices were created on top of storvsc devices. An upstream patch has been applied to fix this bug, and storvsc now returns the correct error code in the described situation. (BZ#1197749) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes several bugs. Documentation for these changes is available from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Updated kernel packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 6.4 Advanced Update Support. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) This issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * When ARP is disabled on an interface with an ARP entry for a neighbor host present in the ARP cache, letting the cached entry expire and attempting to communicate with that neighbor host could cause the host MAC address to not be resolved correctly after ARP is enabled again on the interface. With the following workaround, the entry is not expired and the described scenario works correctly : 1) Add the maximum number of ARP entries you expect for your configuration to the proc/sys/net/ipv4/neigh/default/gc_thresh file. 2) Ensure that relevant IP addresses are put in the ARP cache when the system boots, for example by executing the following two commands : ping [IP address] -c 1 ifconfig ethX -arp (BZ#1207350) * Previously, the open() system call in some cases failed with an EBUSY error if the opened file was also being renamed at the same time. With this update, the kernel automatically retries open() when this failure occurs, and if the retry is not successful either, open() now fails with an ESTALE error. (BZ#1207813) * Previously, a race condition occurred in the build_id_cache__add_s() function, which could truncate system files. A patch has been provided to fix this bug, and system files are no longer truncated in the aforementioned scenario. (BZ#1210591) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2013-7421) A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2014-9644) Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421) Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash). (CVE-2015-1465). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id SUSE_SU-2015-1174-1.NASL
    description The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to fix various bugs and security issues. The following vulnerabilities have been fixed : CVE-2015-3636: A missing sk_nulls_node_init() in ping_unhash() inside the ipv4 stack can cause crashes if a disconnect is followed by another connect() attempt. (bnc#929525) CVE-2015-3339: Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel before 3.19.6 allows local users to gain privileges by executing a setuid program at a time instant when a chown to root is in progress, and the ownership is changed but the setuid bit is not yet stripped. (bnc#928130) CVE-2015-3331: The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket. (bnc#927257) CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message. (bnc#922583) CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16. (bnc#926240) CVE-2015-2150: XSA-120: Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. (bnc#919463) CVE-2015-2042: net/rds/sysctl.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry. (bnc#919018) CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry. (bnc#919007) CVE-2015-1421: Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data. (bnc#915577) CVE-2015-0777: drivers/xen/usbback/usbback.c in 1 -2.6.18-xen-3.4.0 (aka the Xen 3.4.x support patches for the Linux kernel 2.6.18), as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors. (bnc#917830) CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel before 3.18.2 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename. (bnc#918333) CVE-2014-9529: Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. (bnc#912202) CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address. (bnc#911326) CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/. (bnc#914742) CVE-2014-8086: Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. (bnc#900881) Also The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    title SUSE SLED11 / SLES11 Security Update : kernel (SUSE-SU-2015:1174-1)
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2015-0726.NASL
    description From Red Hat Security Advisory 2015:0726 : Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-8159, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat. This update also fixes the following bugs : * In certain systems with multiple CPUs, when a crash was triggered on one CPU with an interrupt handler and this CPU sent Non-Maskable Interrupt (NMI) to another CPU, and, at the same time, ioapic_lock had already been acquired, a deadlock occurred in ioapic_lock. As a consequence, the kdump service could become unresponsive. This bug has been fixed and kdump now works as expected. (BZ#1197742) * On Lenovo X1 Carbon 3rd Gen, X250, and T550 laptops, the thinkpad_acpi module was not properly loaded, and thus the function keys and radio switches did not work. This update applies a new string pattern of BIOS version, which fixes this bug, and function keys and radio switches now work as intended. (BZ#1197743) * During a heavy file system load involving many worker threads, all worker threads in the pool became blocked on a resource, and no manager thread existed to create more workers. As a consequence, the running processes became unresponsive. With this update, the logic around manager creation has been changed to assure that the last worker thread becomes a manager thread and does not start executing work items. Now, a manager thread exists, spawns new workers as needed, and processes no longer hang. (BZ#1197744) * If a thin-pool's metadata enters read-only or fail mode, for example, due to thin-pool running out of metadata or data space, any attempt to make metadata changes such as creating a thin device or snapshot thin device should error out cleanly. However, previously, the kernel code returned verbose and alarming error messages to the user. With this update, due to early trapping of attempt to make metadata changes, informative errors are displayed, no longer unnecessarily alarming the user. (BZ#1197745) * When running Red Hat Enterprise Linux as a guest on Microsoft Hyper-V hypervisor, the storvsc module did not return the correct error code for the upper level Small Computer System Interface (SCSI) subsystem. As a consequence, a SCSI command failed and storvsc did not handle such a failure properly under some conditions, for example, when RAID devices were created on top of storvsc devices. An upstream patch has been applied to fix this bug, and storvsc now returns the correct error code in the described situation. (BZ#1197749) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

  • NASL family SuSE Local Security Checks
    NASL id OPENSUSE-2016-124.NASL
    description The openSUSE 13.1 kernel was updated to receive various security and bugfixes. Following security bugs were fixed : - CVE-2016-0728: A reference leak in keyring handling with join_session_keyring() could lead to local attackers gain root privileges. (bsc#962075). - CVE-2015-7550: A local user could have triggered a race between read and revoke in keyctl (bnc#958951). - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel did not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959190). - CVE-2015-8543: The networking implementation in the Linux kernel did not validate protocol identifiers for certain protocol families, which allowed local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application (bnc#958886). - CVE-2014-8989: The Linux kernel did not properly restrict dropping of supplemental group memberships in certain namespace scenarios, which allowed local users to bypass intended file permissions by leveraging a POSIX ACL containing an entry for the group category that is more restrictive than the entry for the other category, aka a 'negative groups' issue, related to kernel/groups.c, kernel/uid16.c, and kernel/user_namespace.c (bnc#906545). - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on the x86_64 platform mishandles IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by triggering an NMI (bnc#937969). - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936). - CVE-2015-8104: The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c (bnc#954404). - CVE-2015-5307: The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c (bnc#953527). - CVE-2014-9529: Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel allowed local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key (bnc#912202). - CVE-2015-7990: Race condition in the rds_sendmsg function in net/rds/sendmsg.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6937 (bnc#952384 953052). - CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound (bnc#945825). - CVE-2015-7885: The dgnc_mgmt_ioctl function in drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel through 4.3.3 did not initialize a certain structure member, which allowed local users to obtain sensitive information from kernel memory via a crafted application (bnc#951627). - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel did not validate attempted changes to the MTU value, which allowed context-dependent attackers to cause a denial of service (packet loss) via a value that is (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product (bnc#955354). - CVE-2015-8767: A case can occur when sctp_accept() is called by the user during a heartbeat timeout event after the 4-way handshake. Since sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the listening socket but released with the new association socket. The result is a deadlock on any future attempts to take the listening socket lock. (bsc#961509) - CVE-2015-8575: Validate socket address length in sco_sock_bind() to prevent information leak (bsc#959399). - CVE-2015-8551, CVE-2015-8552: xen/pciback: For XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled (bsc#957990). - CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers could have lead to double fetch vulnerabilities, causing denial of service or arbitrary code execution (depending on the configuration) (bsc#957988). The following non-security bugs were fixed : - ALSA: hda - Disable 64bit address for Creative HDA controllers (bnc#814440). - ALSA: hda - Fix noise problems on Thinkpad T440s (boo#958504). - Input: aiptek - fix crash on detecting device without endpoints (bnc#956708). - KEYS: Make /proc/keys unconditional if CONFIG_KEYS=y (boo#956934). - KVM: x86: update masterclock values on TSC writes (bsc#961739). - NFS: Fix a NULL pointer dereference of migration recovery ops for v4.2 client (bsc#960839). - apparmor: allow SYS_CAP_RESOURCE to be sufficient to prlimit another task (bsc#921949). - blktap: also call blkif_disconnect() when frontend switched to closed (bsc#952976). - blktap: refine mm tracking (bsc#952976). - cdrom: Random writing support for BD-RE media (bnc#959568). - genksyms: Handle string literals with spaces in reference files (bsc#958510). - ipv4: Do not increase PMTU with Datagram Too Big message (bsc#955224). - ipv6: distinguish frag queues by device for multicast and link-local packets (bsc#955422). - ipv6: fix tunnel error handling (bsc#952579). - route: Use ipv4_mtu instead of raw rt_pmtu (bsc#955224). - uas: Add response iu handling (bnc#954138). - usbvision fix overflow of interfaces array (bnc#950998). - x86/evtchn: make use of PHYSDEVOP_map_pirq. - xen/pciback: Do not allow MSI-X ops if PCI_COMMAND_MEMORY is not set (bsc#957990 XSA-157).

    description * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important) * A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1421, Important) * It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2014-3690, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-7825, Moderate) * An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. (CVE-2014-7826, Moderate) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory- constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system. (CVE-2014-8884, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) The system must be rebooted for this update to take effect.
