ID CVE-2015-1805
Summary The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows 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."

    description Updated kernel packages that fix multiple 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 implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) * 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 flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low) * It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, 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) * A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low) * An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low) Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of the CVE-2015-1805 issue was discovered by Red Hat. This update also fixes several bugs. Documentation for these changes is available from the following Knowledgebase article: https://access.redhat.com/articles/1469163 All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

(CVE-2015-1805, Important) The security impact of this issue was discovered by Red Hat. This update also fixes the following bugs : * The backlog data could previously not be consumed when the audit_log_start() function was running even if audit_log_start() called the wait_for_auditd() function to consume it. As only auditd could consume the backlog data, audit_log_start() terminated unexpectedly. Consequently, the system became unresponsive until the backlog timeout was up. With this update, audit_log_start() no longer terminates and the system shuts down and reboots gracefully in a timely manner. (BZ#1140489) * Direct I/O writes extending a parallel file could previously race to update the size of the file. If the writes executed in the out-of-order manner, the file size could move backwards and push a previously completed write beyond EOF, causing it to be lost. With this update, file size updates are always executed in appropriate order, thus fixing this bug.

A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) The security impact of this issue was discovered by Red Hat. This update fixes the following bugs : * Due to a bug in the lpfc_device_reset_handler() function, a scsi command timeout could lead to a system crash. With this update, lpfc_device_reset_handler recovers storage without crashing. (BZ#1070964) * Due to the code decrementing the reclaim_in_progress counter without having incremented it first, severe spinlock contention occurred in the shrink_zone() function even though the vm.max_reclaims_in_progress feature was set to 1. This update provides a patch fixing the underlying source code, and spinlock contention no longer occurs in this scenario. (BZ#1164105) * A TCP socket using SACK that had a retransmission but recovered from it, failed to reset the retransmission timestamp. As a consequence, on certain connections, if a packet had to be re-transmitted, the retrans_stamp variable was only cleared when the next acked packet was received. This could lead to an early abortion of the TCP connection if this next packet also got lost. With this update, the socket clears retrans_stamp when the recovery is completed, thus fixing the bug. (BZ#1205521) * Previously, the signal delivery paths did not clear the TS_USEDFPU flag, which could cause problems in the switch_to() function and lead to floating-point unit (FPU) corruption. With this update, TS_USEDFPU is cleared as expected, and FPU is no longer under threat of corruption. (BZ#1193505) * A race condition in the exit_sem() function previously caused the semaphore undo list corruption. As a consequence, a kernel crash could occur. The corruption in the semaphore undo list has been fixed, and the kernel no longer crashes in this situation. (BZ#1124574) * Previously, when running the 'virsh blockresize [Device] [Newsize]' command to resize the disk, the new size was not reflected in a Red Hat Enterprise Linux 5 Virtual Machine (VM). With this update, the new size is now reflected online immediately in a Red Hat Enterprise Linux 5 VM so it is no longer necessary to reboot the VM to see the new disk size. (BZ#1200855) 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 Debian Local Security Checks
    NASL id DEBIAN_DLA-246.NASL
    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.

(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: A 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-2015-4167: The UDF filesystem in the Linux kernel was vulnerable to a crash which could occur while fetching inode information from a corrupted/malicious udf file system image. (bsc#933907). - CVE-2014-9728 CVE-2014-9729 CVE-2014-9730 CVE-2014-9731: Various issues in handling UDF filesystems in the Linux kernel allowed the corruption of kernel memory and other issues. An attacker able to mount a corrupted/malicious UDF file system image could cause the kernel to crash. (bsc#933904 bsc#933896) - CVE-2015-2150: 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 (bsc#919463). - CVE-2015-0777: drivers/xen/usbback/usbback.c as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allowed guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors (bnc#917830). - 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-2015-1805: The Linux kernels implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (bsc#933429). Also The update package also includes non-security fixes.

    description Updated kernel packages that fix multiple security issues, several bugs, and add various enhancements 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. * It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) * A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association. (CVE-2015-3331, Important) * An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage (TLS) during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process. (CVE-2014-9419, Low) * It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low) * An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. (CVE-2014-9585, Low) Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420. The security impact of the CVE-2015-1805 issue was discovered by Red Hat. This update also fixes several bugs and adds various enhancements.

    NASL id SUSE_SU-2015-1478-1.NASL
    description The SUSE Linux Enterprise Server 11 SP2 LTSS kernel was updated to receive various security and bugfixes. 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.

    description Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5. 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. * It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) The security impact of this issue was discovered by Red Hat. This update fixes the following bugs : * Due to a bug in the lpfc_device_reset_handler() function, a scsi command timeout could lead to a system crash. With this update, lpfc_device_reset_handler recovers storage without crashing. (BZ#1070964) * Due to the code decrementing the reclaim_in_progress counter without having incremented it first, severe spinlock contention occurred in the shrink_zone() function even though the vm.max_reclaims_in_progress feature was set to 1. This update provides a patch fixing the underlying source code, and spinlock contention no longer occurs in this scenario. (BZ#1164105) * A TCP socket using SACK that had a retransmission but recovered from it, failed to reset the retransmission timestamp. As a consequence, on certain connections, if a packet had to be re-transmitted, the retrans_stamp variable was only cleared when the next acked packet was received. This could lead to an early abortion of the TCP connection if this next packet also got lost. With this update, the socket clears retrans_stamp when the recovery is completed, thus fixing the bug. (BZ#1205521) * Previously, the signal delivery paths did not clear the TS_USEDFPU flag, which could cause problems in the switch_to() function and lead to floating-point unit (FPU) corruption. With this update, TS_USEDFPU is cleared as expected, and FPU is no longer under threat of corruption. (BZ#1193505) * A race condition in the exit_sem() function previously caused the semaphore undo list corruption. As a consequence, a kernel crash could occur. The corruption in the semaphore undo list has been fixed, and the kernel no longer crashes in this situation. (BZ#1124574) * Previously, when running the 'virsh blockresize [Device] [Newsize]' command to resize the disk, the new size was not reflected in a Red Hat Enterprise Linux 5 Virtual Machine (VM). With this update, the new size is now reflected online immediately in a Red Hat Enterprise Linux 5 VM so it is no longer necessary to reboot the VM to see the new disk size. (BZ#1200855) 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 two security issues and three 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 implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) * A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association. (CVE-2015-3331, Important) The security impact of the CVE-2015-1805 issue was discovered by Red Hat. This update also fixes the following bugs : * Parallel extending direct I/O writes to a file could previously race to update the size of the file. If executed in an incorrect order, the file size could move backwards and push a previously completed write beyond the end of the file, which resulted in losing the write. With this update, file size updates always execute in appropriate order, thus fixing this bug. (BZ#1218498) * When the load rose and run queues were busy due to the effects of the enqueue_entity() function, tasks with large sched_entity.vruntime values could previously be prevented from using the CPU time. A patch eliminating the entity_key() function in the sched_fair.c latency value has been backported from upstream, and all tasks are now provided with fair CPU runtime. (BZ# 1219121) * Previously, running the clock_gettime() function quickly in a loop could result in a jump back in time. Consequently, programs could behave unexpectedly when they assumed that clock_getime() returned an equal or greater time in subsequent calls. With this update, if the time delta between calls is negative, the clock is no longer updated. As a result, a subsequent call to clock_gettime() is guaranteed to return a time greater than or equal to a previous call. (BZ#1219500) 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 privilege escalation, denial of service, information leaks or data corruption. - 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-2015-3636 Wen Xu and wushi of KeenTeam discovered that users allowed to create ping sockets can use them to crash the system and, on 32-bit architectures, for privilege escalation. However, by default, no users on a Debian system have access to ping sockets. - CVE-2015-4167 Carl Henrik Lunde discovered that the UDF implementation is missing a necessary length checks. A local user that can mount devices could use this flaw to crash the system.

    description From Red Hat Security Advisory 2015:1042 : Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5. 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. * It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) The security impact of this issue was discovered by Red Hat. This update fixes the following bugs : * Due to a bug in the lpfc_device_reset_handler() function, a scsi command timeout could lead to a system crash. With this update, lpfc_device_reset_handler recovers storage without crashing. (BZ#1070964) * Due to the code decrementing the reclaim_in_progress counter without having incremented it first, severe spinlock contention occurred in the shrink_zone() function even though the vm.max_reclaims_in_progress feature was set to 1. This update provides a patch fixing the underlying source code, and spinlock contention no longer occurs in this scenario. (BZ#1164105) * A TCP socket using SACK that had a retransmission but recovered from it, failed to reset the retransmission timestamp. As a consequence, on certain connections, if a packet had to be re-transmitted, the retrans_stamp variable was only cleared when the next acked packet was received. This could lead to an early abortion of the TCP connection if this next packet also got lost. With this update, the socket clears retrans_stamp when the recovery is completed, thus fixing the bug. (BZ#1205521) * Previously, the signal delivery paths did not clear the TS_USEDFPU flag, which could cause problems in the switch_to() function and lead to floating-point unit (FPU) corruption. With this update, TS_USEDFPU is cleared as expected, and FPU is no longer under threat of corruption. (BZ#1193505) * A race condition in the exit_sem() function previously caused the semaphore undo list corruption. As a consequence, a kernel crash could occur. The corruption in the semaphore undo list has been fixed, and the kernel no longer crashes in this situation. (BZ#1124574) * Previously, when running the 'virsh blockresize [Device] [Newsize]' command to resize the disk, the new size was not reflected in a Red Hat Enterprise Linux 5 Virtual Machine (VM). With this update, the new size is now reflected online immediately in a Red Hat Enterprise Linux 5 VM so it is no longer necessary to reboot the VM to see the new disk size. (BZ#1200855) 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 - It was found that the fix for CVE-2015-1805 incorrectly kept buffer offset and buffer length in sync on a failed atomic read, potentially resulting in a pipe buffer state corruption. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space. (CVE-2016-0774, Moderate) This update also fixes the following bugs : - In the anon_vma structure, the degree counts number of child anon_vmas and of VMAs which points to this anon_vma. Failure to decrement the parent's degree in the unlink_anon_vma() function, when its list was empty, previously triggered a BUG_ON() assertion. The provided patch makes sure the anon_vma degree is always decremented when the VMA list is empty, thus fixing this bug. - When running Internet Protocol Security (IPSEC) on external storage encrypted with LUKS under a substantial load on the system, data corruptions could previously occur. A set of upstream patches has been provided, and data corruption is no longer reported in this situation. - Due to prematurely decremented calc_load_task, the calculated load average was off by up to the number of CPUs in the machine. As a consequence, job scheduling worked improperly causing a drop in the system performance. This update keeps the delta of the CPU going into NO_HZ idle separately, and folds the pending idle delta into the global active count while correctly aging the averages for the idle-duration when leaving NO_HZ mode. Now, job scheduling works correctly, ensuring balanced CPU load. - Due to a regression in the Scientific Linux 6.7 kernel, the cgroup OOM notifier accessed a cgroup-specific internal data structure without a proper locking protection, which led to a kernel panic. This update adjusts the cgroup OOM notifier to lock internal data properly, thus fixing the bug. - GFS2 had a rare timing window that sometimes caused it to reference an uninitialized variable. Consequently, a kernel panic occurred. The code has been changed to reference the correct value during this timing window, and the kernel no longer panics. - Due to a race condition whereby a cache operation could be submitted after a cache object was killed, the kernel occasionally crashed on systems running the cachefilesd service. The provided patch prevents the race condition by adding serialization in the code that makes the object unavailable. As a result, all subsequent operations targetted on the object are rejected and the kernel no longer crashes in this scenario. This update also adds this enhancement : - The lpfc driver has been updated to version 11.0.0.4. The system must be rebooted for this update to take effect.
