  • 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).

  • NASL family Mandriva Local Security Checks
    NASL id MANDRIVA_MDVSA-2015-058.NASL
    description Multiple vulnerabilities has been found and corrected in the Linux kernel : The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644 (CVE-2013-7421). arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU (CVE-2014-3690). arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in the Linux kernel through 3.18.1 allows local users to bypass the espfix protection mechanism, and consequently makes it easier for local users to bypass the ASLR protection mechanism, via a crafted application that makes a set_thread_area system call and later reads a 16-bit value (CVE-2014-8133). net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers (CVE-2014-8160). The Linux kernel through 3.17.4 does not properly restrict dropping of supplemental group memberships in certain namespace scenarios, which allows 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 (CVE-2014-8989). 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 (CVE-2014-9419). The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image (CVE-2014-9420). The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets (CVE-2014-9428). 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 (CVE-2014-9529). The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 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 iso9660 image (CVE-2014-9584). The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD (CVE-2014-9585). The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a parenthesized module template expression in the salg_name field, as demonstrated by the vfat(aes) expression, a different vulnerability than CVE-2013-7421 (CVE-2014-9644). 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 (CVE-2014-9683). The em_sysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service (guest OS crash) by triggering use of a 16-bit code segment for emulation of a SYSENTER instruction (CVE-2015-0239). The updated packages provides a solution for these security 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.

    description USN-2515-1 fixed vulnerabilities in the Linux kernel. There was an unrelated regression in the use of the virtual counter (CNTVCT) on arm64 architectures. This update fixes the problem. We apologize for the inconvenience. A flaw was discovered in the Kernel Virtual Machine's (KVM) emulation of the SYSTENTER instruction when the guest OS does not initialize the SYSENTER MSRs. A guest OS user could exploit this flaw to cause a denial of service of the guest OS (crash) or potentially gain privileges on the guest OS. (CVE-2015-0239) Andy Lutomirski discovered an information leak in the Linux kernel's Thread Local Storage (TLS) implementation allowing users to bypass the espfix to obtain information that could be used to bypass the Address Space Layout Randomization (ASLR) protection mechanism. A local user could exploit this flaw to obtain potentially sensitive information from kernel memory. (CVE-2014-8133) A restriction bypass was discovered in iptables when conntrack rules are specified and the conntrack protocol handler module is not loaded into the Linux kernel. This flaw can cause the firewall rules on the system to be bypassed when conntrack rules are used. (CVE-2014-8160) A flaw was discovered with file renaming in the linux kernel. A local user could exploit this flaw to cause a denial of service (deadlock and system hang). (CVE-2014-8559) A flaw was discovered in how supplemental group memberships are handled in certain namespace scenarios. A local user could exploit this flaw to bypass file permission restrictions. (CVE-2014-8989) A flaw was discovered in how Thread Local Storage (TLS) is handled by the task switching function in the Linux kernel for x86_64 based machines. A local user could exploit this flaw to bypass the Address Space Layout Radomization (ASLR) protection mechanism. (CVE-2014-9419) Prasad J Pandit reported a flaw in the rock_continue function of the Linux kernel's ISO 9660 CDROM file system. A local user could exploit this flaw to cause a denial of service (system crash or hang). (CVE-2014-9420) A flaw was discovered in the fragment handling of the B.A.T.M.A.N. Advanced Meshing Protocol in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (mesh-node system crash) via fragmented packets. (CVE-2014-9428) A race condition was discovered in the Linux kernel's key ring. A local user could cause a denial of service (memory corruption or panic) or possibly have unspecified impact via the keyctl commands. (CVE-2014-9529) A memory leak was discovered in the ISO 9660 CDROM file system when parsing rock ridge ER records. A local user could exploit this flaw to obtain sensitive information from kernel memory via a crafted iso9660 image. (CVE-2014-9584) A flaw was discovered in the Address Space Layout Randomization (ASLR) of the Virtual Dynamically linked Shared Objects (vDSO) location. This flaw makes it easier for a local user to bypass the ASLR protection mechanism. (CVE-2014-9585) Dmitry Chernenkov discovered a buffer overflow in eCryptfs' encrypted file name decoding. A local unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges. (CVE-2014-9683).

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3170.NASL
    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.

    description USN-2516-1 fixed vulnerabilities in the Linux kernel. There was an unrelated regression in the use of the virtual counter (CNTVCT) on arm64 architectures. This update fixes the problem. We apologize for the inconvenience. A flaw was discovered in the Kernel Virtual Machine's (KVM) emulation of the SYSTENTER instruction when the guest OS does not initialize the SYSENTER MSRs. A guest OS user could exploit this flaw to cause a denial of service of the guest OS (crash) or potentially gain privileges on the guest OS.

    description The linux-2.6 update issued as DLA-246-1 caused regressions. This update corrects the defective patches applied in that update causing these problems. For reference the original advisory text follows. This update fixes the CVEs described below. CVE-2011-5321 Jiri Slaby discovered that tty_driver_lookup_tty() may leak a reference to the tty driver. A local user could use this flaw to crash the system. CVE-2012-6689 Pablo Neira Ayuso discovered that non-root user-space processes can send forged Netlink notifications to other processes. A local user could use this flaw for denial of service or privilege escalation. CVE-2014-3184 Ben Hawkes discovered that various HID drivers may over-read the report descriptor buffer, possibly resulting in a crash if a HID with a crafted descriptor is plugged in. CVE-2014-8159 It was found that the Linux kernel's InfiniBand/RDMA 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-2014-9683 Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service. CVE-2014-9728 / CVE-2014-9729 / CVE-2014-9730 / CVE-2014-9731 / CVE-2015-4167 Carl Henrik Lunde discovered that the UDF implementation is missing several necessary length checks. A local user that can mount devices could use these various flaws to crash the system, to leak information from the kernel, or possibly for privilege escalation. CVE-2015-1805 Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation. This may also result in data corruption and information leaks in pipes between non-malicious processes. CVE-2015-2041 Sasha Levin discovered that the LLC subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this possibly allows privilege escalation from a process with CAP_NET_ADMIN capability; it also results in a trivial information leak. CVE-2015-2042 Sasha Levin discovered that the RDS subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this results in a trivial information leak. CVE-2015-2830 Andrew Lutomirski discovered that when a 64-bit task on an amd64 kernel makes a fork(2) or clone(2) system call using int $0x80, the 32-bit compatibility flag is set (correctly) but is not cleared on return. As a result, both seccomp and audit will misinterpret the following system call by the task(s), possibly leading to a violation of security policy. CVE-2015-2922 Modio AB discovered that the IPv6 subsystem would process a router advertisement that specifies no route but only a hop limit, which would then be applied to the interface that received it. This can result in loss of IPv6 connectivity beyond the local network. This may be mitigated by disabling processing of IPv6 router advertisements if they are not needed: sysctl net.ipv6.conf.default.accept_ra=0 sysctl net.ipv6.conf..accept_ra=0 CVE-2015-3339 It was found that the execve(2) system call can race with inode attribute changes made by chown(2). Although chown(2) clears the setuid/setgid bits of a file if it changes the respective owner ID, this race condition could result in execve(2) setting effective uid/gid to the new owner ID, a privilege escalation. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze12. For the oldstable distribution (wheezy), these problems were fixed in linux version 3.2.68-1+deb7u1 or earlier, except for CVE-2015-1805 and CVE-2015-4167 which will be fixed soon. For the stable distribution (jessie), these problems were fixed in linux version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later. We recommend that you upgrade your linux-2.6 packages. 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.

    description Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the seventh regular update. Red Hat Product Security has rated this update as having Moderate 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 Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-9683, Moderate) * A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate) * Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low) * An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low) * It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8133, Low) * An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. (CVE-2014-8709, Low) * It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Red Hat Enterprise Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor. (CVE-2015-0239, Low) Red Hat would like to thank Andy Lutomirski for reporting the CVE-2014-8133 issue, and Nadav Amit for reporting the CVE-2015-0239 issue. This update fixes several hundred bugs and adds numerous enhancements. Refer to the Red Hat Enterprise Linux 6.7 Release Notes for information on the most significant of these changes, and the following Knowledgebase article for further information : https://access.redhat.com/articles/1466073 All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

    title openSUSE Security Update : Linux Kernel (openSUSE-2015-302)
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2015-1272.NASL
    description Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the seventh regular update. Red Hat Product Security has rated this update as having Moderate 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 Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-9683, Moderate) * A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate) * Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low) * An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low) * It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8133, Low) * An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. (CVE-2014-8709, Low) * It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Red Hat Enterprise Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor. (CVE-2015-0239, Low) Red Hat would like to thank Andy Lutomirski for reporting the CVE-2014-8133 issue, and Nadav Amit for reporting the CVE-2015-0239 issue. This update fixes several hundred bugs and adds numerous enhancements. Refer to the Red Hat Enterprise Linux 6.7 Release Notes for information on the most significant of these changes, and the following Knowledgebase article for further information : https://access.redhat.com/articles/1466073 All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

    title CentOS 6 : kernel (CESA-2015:1272)
  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-2518-1.NASL
    description A flaw was discovered in the Kernel Virtual Machine's (KVM) emulation of the SYSTENTER instruction when the guest OS does not initialize the SYSENTER MSRs. A guest OS user could exploit this flaw to cause a denial of service of the guest OS (crash) or potentially gain privileges on the guest OS. (CVE-2015-0239) Andy Lutomirski discovered an information leak in the Linux kernel's Thread Local Storage (TLS) implementation allowing users to bypass the espfix to obtain information that could be used to bypass the Address Space Layout Randomization (ASLR) protection mechanism. A local user could exploit this flaw to obtain potentially sensitive information from kernel memory. (CVE-2014-8133) A restriction bypass was discovered in iptables when conntrack rules are specified and the conntrack protocol handler module is not loaded into the Linux kernel. This flaw can cause the firewall rules on the system to be bypassed when conntrack rules are used. (CVE-2014-8160) A flaw was discovered with file renaming in the linux kernel. A local user could exploit this flaw to cause a denial of service (deadlock and system hang). (CVE-2014-8559) A flaw was discovered in how supplemental group memberships are handled in certain namespace scenarios. A local user could exploit this flaw to bypass file permission restrictions. (CVE-2014-8989) A flaw was discovered in how Thread Local Storage (TLS) is handled by the task switching function in the Linux kernel for x86_64 based machines. A local user could exploit this flaw to bypass the Address Space Layout Radomization (ASLR) protection mechanism. (CVE-2014-9419) Prasad J Pandit reported a flaw in the rock_continue function of the Linux kernel's ISO 9660 CDROM file system. A local user could exploit this flaw to cause a denial of service (system crash or hang). (CVE-2014-9420) A flaw was discovered in the fragment handling of the B.A.T.M.A.N. Advanced Meshing Protocol in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (mesh-node system crash) via fragmented packets. (CVE-2014-9428) A race condition was discovered in the Linux kernel's key ring. A local user could cause a denial of service (memory corruption or panic) or possibly have unspecified impact via the keyctl commands. (CVE-2014-9529) A memory leak was discovered in the ISO 9660 CDROM file system when parsing rock ridge ER records. A local user could exploit this flaw to obtain sensitive information from kernel memory via a crafted iso9660 image. (CVE-2014-9584) A flaw was discovered in the Address Space Layout Randomization (ASLR) of the Virtual Dynamically linked Shared Objects (vDSO) location. This flaw makes it easier for a local user to bypass the ASLR protection mechanism. (CVE-2014-9585) Dmitry Chernenkov discovered a buffer overflow in eCryptfs' encrypted file name decoding. A local unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges. (CVE-2014-9683). 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.
