    description From Red Hat Security Advisory 2016:2006 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. (CVE-2016-5829, Moderate) The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). Bug Fix(es) : * Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962) * In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036) * Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state : The numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing. The blocks were not actually missing, but they were left in the 'unlinked' state. In some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic. If an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption. With this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore. (BZ#1359037) * Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock. This occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038) * When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions. As a result, the error messages no longer appear when there is a change in the status of one of the arrays. (BZ#1359039)

    description An update for kernel-rt is now available for Red Hat Enterprise MRG 2.5. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application. (CVE-2015-8660, Moderate) Red Hat would like to thank Nathan Williams for reporting CVE-2015-8660. The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). The kernel-rt packages have been upgraded to upstream version 3.10.0-327.rt56.194.el6rt, which provides a number of bug fixes over the previous version. (BZ#1343658) This update also fixes the following bugs : * Previously, use of the get/put_cpu_var() function in function refill_stock() from the memcontrol cgroup code lead to a 'scheduling while atomic' warning. With this update, refill_stock() uses the get/put_cpu_light() function instead, and the warnings no longer appear. (BZ#1348710) * Prior to this update, if a real time task pinned to a given CPU was taking 100% of the CPU time, then calls to the lru_add_drain_all() function on other CPUs blocked for an undetermined amount of time. This caused latencies and undesired side effects. With this update, lru_add_drain_all() has been changed to drain the LRU pagevecs of remote CPUs. (BZ#1348711)

    description This update for the Linux Kernel 3.12.48-52_27 fixes several issues. The following security bugs were fixed : - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bsc#984764). - CVE-2016-1583: The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling (bsc#983144). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relied on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bsc#980883). - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bsc#980856). - CVE-2015-8019: The skb_copy_and_csum_datagram_iovec function in net/core/datagram.c in the Linux kernel did not accept a length argument, which allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a write system call followed by a recvmsg system call (bsc#979078). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bsc#979074). - CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in the Linux kernel did not properly maintain a hub-interface data structure, which allowed physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device (bsc#979064). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bsc#971793). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bsc#973570, bsc#955837).

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DLA-609.NASL
    description This update fixes the CVEs described below. CVE-2016-3857 Chiachih Wu reported two bugs in the ARM OABI compatibility layer that can be used by local users for privilege escalation. The OABI compatibility layer is enabled in all kernel flavours for armel and armhf. CVE-2016-4470 Wade Mealing of the Red Hat Product Security Team reported that in some error cases the KEYS subsystem will dereference an uninitialised pointer. A local user can use the keyctl() system call for denial of service (crash) or possibly for privilege escalation. CVE-2016-5696 Yue Cao, Zhiyun Qian, Zhongjie Wang, Tuan Dao, and Srikanth V. Krishnamurthy of the University of California, Riverside; and Lisa M. Marvel of the United States Army Research Laboratory discovered that Linux's implementation of the TCP Challenge ACK feature results in a side channel that can be used to find TCP connections between specific IP addresses, and to inject messages into those connections. Where a service is made available through TCP, this may allow remote attackers to impersonate another connected user to the server or to impersonate the server to another connected user. In case the service uses a protocol with message authentication (e.g. TLS or SSH), this vulnerability only allows denial of service (connection failure). An attack takes tens of seconds, so short-lived TCP connections are also unlikely to be vulnerable. This may be mitigated by increasing the rate limit for TCP Challenge ACKs so that it is never exceeded: sysctl net.ipv4.tcp_challenge_ack_limit=1000000000 CVE-2016-5829 Several heap-based buffer overflow vulnerabilities were found in the hiddev driver, allowing a local user with access to a HID device to cause a denial of service or potentially escalate their privileges. CVE-2016-6136 Pengfei Wang discovered that the audit subsystem has a 'double-fetch' or 'TOCTTOU' bug in its handling of special characters in the name of an executable. Where audit logging of execve() is enabled, this allows a local user to generate misleading log messages. CVE-2016-6480 Pengfei Wang discovered that the aacraid driver for Adaptec RAID controllers has a 'double-fetch' or 'TOCTTOU' bug in its validation of 'FIB' messages passed through the ioctl() system call. This has no practical security impact in current Debian releases. CVE-2016-6828 Marco Grassi reported a 'use-after-free' bug in the TCP implementation, which can be triggered by local users. The security impact is unclear, but might include denial of service or privilege escalation. CVE-2016-7118 Marcin Szewczyk reported that calling fcntl() on a file descriptor for a directory on an aufs filesystem would result in am 'oops'. This allows local users to cause a denial of service. This is a Debian-specific regression introduced in version 3.2.81-1. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.81-2. This version also fixes a build failure (bug #827561) for custom kernels with CONFIG_MODULES disabled, a regression in version 3.2.81-1. It also updates the PREEMPT_RT featureset to version 3.2.81-rt117. For Debian 8 'Jessie', CVE-2016-3857 has no impact; CVE-2016-4470 and CVE-2016-5829 were fixed in linux version 3.16.7-ckt25-2+deb8u3 or earlier; and the remaining issues are fixed in version 3.16.36-1+deb8u1. We recommend that you upgrade your linux packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

    title openSUSE Security Update : the Linux Kernel (openSUSE-2016-1015)
  • NASL family Scientific Linux Local Security Checks
    NASL id SL_20160802_KERNEL_ON_SL7_X.NASL
    description To see the complete list of bug fixes, users are directed to the related Knowledge Article : Security Fix(es) : - A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) - The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application. (CVE-2015-8660, Moderate) - It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Bug Fix(es) : - The glibc headers and the Linux headers share certain definitions of key structures that are required to be defined in kernel and in userspace. In some instances both userspace and sanitized kernel headers have to be included in order to get the structure definitions required by the user program. Unfortunately because the glibc and Linux headers don't coordinate this can result in compilation errors. The glibc headers have therefore been fixed to coordinate with Linux UAPI-based headers. With the header coordination compilation errors no longer occur. - When running the TCP/IPv6 traffic over the mlx4_en networking interface on the big endian architectures, call traces reporting about a 'hw csum failure' could occur. With this update, the mlx4_en driver has been fixed by correction of the checksum calculation for the big endian architectures. As a result, the call trace error no longer appears in the log messages. - Under significant load, some applications such as logshifter could generate bursts of log messages too large for the system logger to spool. Due to a race condition, log messages from that application could then be lost even after the log volume dropped to manageable levels. This update fixes the kernel mechanism used to notify the transmitter end of the socket used by the system logger that more space is available on the receiver side, removing a race condition which previously caused the sender to stop transmitting new messages and allowing all log messages to be processed correctly. - Previously, after heavy open or close of the Accelerator Function Unit (AFU) contexts, the interrupt packet went out and the AFU context did not see any interrupts. Consequently, a kernel panic could occur. The provided patch set fixes handling of the interrupt requests, and kernel panic no longer occurs in the described situation. - net: recvfrom would fail on short buffer. - Backport rhashtable changes from upstream. - Server Crashing after starting Glusterd & creating volumes. - RAID5 reshape deadlock fix. - BDX perf uncore support fix.

    description This update for the Linux Kernel 3.12.55-52_45 fixes several issues. The following security bugs were fixed : - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bsc#984764). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relied on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bsc#980883). - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bsc#980856). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bsc#979074). - CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in the Linux kernel did not properly maintain a hub-interface data structure, which allowed physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device (bsc#979064). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bsc#971793). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bsc#973570, bsc#955837). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2016-1541.NASL
    description An update for kernel-rt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application. (CVE-2015-8660, Moderate) Red Hat would like to thank Nathan Williams for reporting CVE-2015-8660. The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). The kernel-rt packages have been upgraded to the kernel-3.10.0-327.28.2.el7 source tree, which provides a number of bug fixes over the previous version. (BZ#1350307) This update also fixes the following bugs : * Previously, use of the get/put_cpu_var() function in function refill_stock() from the memcontrol cgroup code lead to a 'scheduling while atomic' warning. With this update, refill_stock() uses the get/put_cpu_light() function instead, and the warnings no longer appear. (BZ#1347171) * Prior to this update, if a real time task pinned to a given CPU was taking 100% of the CPU time, then calls to the lru_add_drain_all() function on other CPUs blocked for an undetermined amount of time. This caused latencies and undesired side effects. With this update, lru_add_drain_all() has been changed to drain the LRU pagevecs of remote CPUs. (BZ#1348523)

    description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. (CVE-2016-5829, Moderate) The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). Bug Fix(es) : * Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ#1366962) * In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. (BZ#1359036) * Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state : The numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing. The blocks were not actually missing, but they were left in the 'unlinked' state. In some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic. If an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption. With this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore. (BZ#1359037) * Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock. This occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. (BZ#1359038) * When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions. As a result, the error messages no longer appear when there is a change in the status of one of the arrays. (BZ#1359039)

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2016-1539.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. These updated kernel packages include several security issues and numerous bug fixes, some of which you can see below. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article: https://access.redhat.com/articles/2460971. Security Fix(es) : * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application. (CVE-2015-8660, Moderate) * It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Red Hat would like to thank Nathan Williams for reporting CVE-2015-8660. The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). Bug Fix(es) : * The glibc headers and the Linux headers share certain definitions of key structures that are required to be defined in kernel and in userspace. In some instances both userspace and sanitized kernel headers have to be included in order to get the structure definitions required by the user program. Unfortunately because the glibc and Linux headers don't coordinate this can result in compilation errors. The glibc headers have therefore been fixed to coordinate with Linux UAPI-based headers. With the header coordination compilation errors no longer occur. (BZ#1331285) * When running the TCP/IPv6 traffic over the mlx4_en networking interface on the big endian architectures, call traces reporting about a 'hw csum failure' could occur. With this update, the mlx4_en driver has been fixed by correction of the checksum calculation for the big endian architectures. As a result, the call trace error no longer appears in the log messages. (BZ#1337431) * Under significant load, some applications such as logshifter could generate bursts of log messages too large for the system logger to spool. Due to a race condition, log messages from that application could then be lost even after the log volume dropped to manageable levels. This update fixes the kernel mechanism used to notify the transmitter end of the socket used by the system logger that more space is available on the receiver side, removing a race condition which previously caused the sender to stop transmitting new messages and allowing all log messages to be processed correctly. (BZ#1337513) * Previously, after heavy open or close of the Accelerator Function Unit (AFU) contexts, the interrupt packet went out and the AFU context did not see any interrupts. Consequently, a kernel panic could occur. The provided patch set fixes handling of the interrupt requests, and kernel panic no longer occurs in the described situation. (BZ#1338886) * net: recvfrom would fail on short buffer. (BZ#1339115) * Backport rhashtable changes from upstream. (BZ#1343639) * Server Crashing after starting Glusterd & creating volumes. (BZ#1344234) * RAID5 reshape deadlock fix. (BZ#1344313) * BDX perf uncore support fix. (BZ#1347374)

    NASL id DEBIAN_DSA-3607.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-7515, CVE-2016-2184, CVE-2016-2185, CVE-2016-2186, CVE-2016-2187, CVE-2016-3136, CVE-2016-3137, CVE-2016-3138, CVE-2016-3140 Ralf Spenneberg of OpenSource Security reported that various USB drivers do not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash). - CVE-2016-0821 Solar Designer noted that the list 'poisoning' feature, intended to mitigate the effects of bugs in list manipulation in the kernel, used poison values within the range of virtual addresses that can be allocated by user processes. - CVE-2016-1237 David Sinquin discovered that nfsd does not check permissions when setting ACLs, allowing users to grant themselves permissions to a file by setting the ACL. - CVE-2016-1583 Jann Horn of Google Project Zero reported that the eCryptfs filesystem could be used together with the proc filesystem to cause a kernel stack overflow. If the ecryptfs-utils package is installed, local users could exploit this, via the mount.ecryptfs_private program, for denial of service (crash) or possibly for privilege escalation. - CVE-2016-2117 Justin Yackoski of Cryptonite discovered that the Atheros L2 ethernet driver incorrectly enables scatter/gather I/O. A remote attacker could take advantage of this flaw to obtain potentially sensitive information from kernel memory. - CVE-2016-2143 Marcin Koscielnicki discovered that the fork implementation in the Linux kernel on s390 platforms mishandles the case of four page-table levels, which allows local users to cause a denial of service (system crash). - CVE-2016-3070 Jan Stancek of Red Hat discovered a local denial of service vulnerability in AIO handling. - CVE-2016-3134 The Google Project Zero team found that the netfilter subsystem does not sufficiently validate filter table entries. A user with the CAP_NET_ADMIN capability could use this for denial of service (crash) or possibly for privilege escalation. Debian disables unprivileged user namespaces by default, if locally enabled with the kernel.unprivileged_userns_clone sysctl, this allows privilege escalation. - CVE-2016-3156 Solar Designer discovered that the IPv4 implementation in the Linux kernel did not perform the destruction of inet device objects properly. An attacker in a guest OS could use this to cause a denial of service (networking outage) in the host OS. - CVE-2016-3157 / XSA-171 Andy Lutomirski discovered that the x86_64 (amd64) task switching implementation did not correctly update the I/O permission level when running as a Xen paravirtual (PV) guest. In some configurations this would allow local users to cause a denial of service (crash) or to escalate their privileges within the guest. - CVE-2016-3672 Hector Marco and Ismael Ripoll noted that it was possible to disable Address Space Layout Randomisation (ASLR) for x86_32 (i386) programs by removing the stack resource limit. This made it easier for local users to exploit security flaws in programs that have the setuid or setgid flag set. - CVE-2016-3951 It was discovered that the cdc_ncm driver would free memory prematurely if certain errors occurred during its initialisation. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash) or possibly to escalate their privileges. - CVE-2016-3955 Ignat Korchagin reported that the usbip subsystem did not check the length of data received for a USB buffer. This allowed denial of service (crash) or privilege escalation on a system configured as a usbip client, by the usbip server or by an attacker able to impersonate it over the network. A system configured as a usbip server might be similarly vulnerable to physically present users. - CVE-2016-3961 / XSA-174 Vitaly Kuznetsov of Red Hat discovered that Linux allowed the use of hugetlbfs on x86 (i386 and amd64) systems even when running as a Xen paravirtualised (PV) guest, although Xen does not support huge pages. This allowed users with access to /dev/hugepages to cause a denial of service (crash) in the guest. - CVE-2016-4470 David Howells of Red Hat discovered that a local user can trigger a flaw in the Linux kernel's handling of key lookups in the keychain subsystem, leading to a denial of service (crash) or possibly to privilege escalation. - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486, CVE-2016-4569, CVE-2016-4578, CVE-2016-4580, CVE-2016-5243, CVE-2016-5244 Kangjie Lu reported that the USB devio, llc, rtnetlink, ALSA timer, x25, tipc, and rds facilities leaked information from the kernel stack. - CVE-2016-4565 Jann Horn of Google Project Zero reported that various components in the InfiniBand stack implemented unusual semantics for the write() operation. On a system with InfiniBand drivers loaded, local users could use this for denial of service or privilege escalation. - CVE-2016-4581 Tycho Andersen discovered that in some situations the Linux kernel did not handle propagated mounts correctly. A local user can take advantage of this flaw to cause a denial of service (system crash). - CVE-2016-4805 Baozeng Ding discovered a use-after-free in the generic PPP layer in the Linux kernel. A local user can take advantage of this flaw to cause a denial of service (system crash), or potentially escalate their privileges. - CVE-2016-4913 Al Viro found that the ISO9660 filesystem implementation did not correctly count the length of certain invalid name entries. Reading a directory containing such name entries would leak information from kernel memory. Users permitted to mount disks or disk images could use this to obtain sensitive information. - CVE-2016-4997 / CVE-2016-4998 Jesse Hertz and Tim Newsham discovered that missing input sanitising in Netfilter socket handling may result in denial of service. Debian disables unprivileged user namespaces by default, if locally enabled with the kernel.unprivileged_userns_clone sysctl, this also allows privilege escalation.

    description An update for kernel is now available for Red Hat Enterprise Linux 6.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. (CVE-2016-4470, Important) * A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. (CVE-2016-5195, Important) Red Hat would like to thank Phil Oester for reporting CVE-2016-5195. The CVE-2016-4470 issue was discovered by David Howells (Red Hat). Enhancement(s) : * This update fixes a tape write problem by fixing the use of the sas_is_tlr_enabled API in the mpt3sas driver. The driver now checks whether Transport Layer Recovery (TLR) is enabled before enabling the MPI2_SCSIIO_CONTROL_TLR_ON flag. (BZ#1372352)

CVE-2014-9904: The snd_compress_check_input function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel did not properly check for an integer overflow, which allowed local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call (bnc#986811). - CVE-2016-5829: Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call (bnc#986572). - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bnc#984755). 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 Security Fix(es) : - A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) - A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. (CVE-2016-5829, Moderate) The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). Bug Fix(es) : - Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. - In some circumstances, resetting a Fibre Channel over Ethernet (FCoE) interface could lead to a kernel panic, due to invalid information extracted from the FCoE header. This update adds santiy checking to the cpu number extracted from the FCoE header. This ensures that subsequent operations address a valid cpu, and eliminates the kernel panic. - Prior to this update, the following problems occurred with the way GSF2 transitioned files and directories from the 'unlinked' state to the 'free' state : The numbers reported for the df and the du commands in some cases got out of sync, which caused blocks in the file system to appear missing. The blocks were not actually missing, but they were left in the 'unlinked' state. In some circumstances, GFS2 referenced a cluster lock that was already deleted, which led to a kernel panic. If an object was deleted and its space reused as a different object, GFS2 sometimes deleted the existing one, which caused file system corruption. With this update, the transition from 'unlinked' to 'free' state has been fixed. As a result, none of these three problems occur anymore. - Previously, the GFS2 file system in some cases became unresponsive due to lock dependency problems between inodes and the cluster lock. This occurred most frequently on nearly full file systems where files and directories were being deleted and recreated at the same block location at the same time. With this update, a set of patches has been applied to fix these lock dependencies. As a result, GFS2 no longer hangs in the described circumstances. - When used with controllers that do not support DCMD- MR_DCMD_PD_LIST_QUERY, the megaraid_sas driver can go into infinite error reporting loop of error reporting messages. This could cause difficulties with finding other important log messages, or even it could cause the disk to overflow. This bug has been fixed by ignoring the DCMD MR_DCMD_PD_LIST_QUERY query for controllers which do not support it and sending the DCMD SUCCESS status to the AEN functions. As a result, the error messages no longer appear when there is a change in the status of one of the arrays.

    description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696) - A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470) - A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.(CVE-2016-4565) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
