    description From Red Hat Security Advisory 2014:0786 : Updated kernel packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important) * A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important) * Use-after-free and information leak flaws were found in the way the Linux kernel's floppy driver processed the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use these flaws to escalate their privileges on the system. (CVE-2014-1737, CVE-2014-1738, Important) * It was found that the aio_read_events_ring() function of the Linux kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO ring head received from user space. A local, unprivileged user could use this flaw to disclose random parts of the (physical) memory belonging to the kernel and/or other processes. (CVE-2014-0206, Moderate) * An out-of-bounds memory access flaw was found in the Netlink Attribute extension of the Berkeley Packet Filter (BPF) interpreter functionality in the Linux kernel's networking implementation. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145, Moderate) * An information leak flaw was found in the way the skb_zerocopy() function copied socket buffers (skb) that are backed by user-space buffers (for example vhost-net and Xen netback), potentially allowing an attacker to read data from those buffers. (CVE-2014-2568, Low) Red Hat would like to thank Kees Cook of Google for reporting CVE-2014-3153 and Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. Google acknowledges Pinkie Pie as the original reporter of CVE-2014-3153. The CVE-2014-0206 issue was discovered by Mateusz Guzik of Red Hat. This update also fixes the following bugs : * Due to incorrect calculation of Tx statistics in the qlcninc driver, running the 'ethtool -S ethX' command could trigger memory corruption. As a consequence, running the sosreport tool, that uses this command, resulted in a kernel panic. The problem has been fixed by correcting the said statistics calculation. (BZ#1104972) * When an attempt to create a file on the GFS2 file system failed due to a file system quota violation, the relevant VFS inode was not completely uninitialized. This could result in a list corruption error. This update resolves this problem by correctly uninitializing the VFS inode in this situation. (BZ#1097407) * Due to a race condition in the kernel, the getcwd() system call could return '/' instead of the correct full path name when querying a path name of a file or directory. Paths returned in the '/proc' file system could also be incorrect. This problem was causing instability of various applications. The aforementioned race condition has been fixed and getcwd() now always returns the correct paths. (BZ#1099048) In addition, this update adds the following enhancements : * The kernel mutex code has been improved. The changes include improved queuing of the MCS spin locks, the MCS code optimization, introduction of the cancellable MCS spin locks, and improved handling of mutexes without wait locks. (BZ#1103631, BZ#1103629) * The handling of the Virtual Memory Area (VMA) cache and huge page faults has been improved. (BZ#1103630) 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.

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-rt packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important) * It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. Note that this issue only affected systems using an Intel CPU. (CVE-2014-4699, Important) * It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate) * It was found that the aio_read_events_ring() function of the Linux kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO ring head received from user space.

(CVE-2014-3144, CVE-2014-3145, Moderate) * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) * 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) * An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made. (CVE-2014-4667, Moderate) * An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) back-end driver of the iSCSI Target subsystem of the Linux kernel. A privileged user could use this flaw to leak the contents of kernel memory to an iSCSI initiator remote client. (CVE-2014-4027, Low) Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.43 and correct these issues.

    description arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. Array index error in the aio_read_events_ring function in fs/aio.c in the Linux kernel through 3.15.1 allows local users to obtain sensitive information from kernel memory via a large head value. The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root. ** DISPUTED ** Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. NOTE: the author of the LZO algorithms says 'the Linux kernel is *not* affected; media hype.'

CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allowed local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. CVE-2014-5206: The do_remount function in fs/namespace.c in the Linux kernel did not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allowed local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a 'mount -o remount' command within a user namespace. CVE-2014-5207: fs/namespace.c in the Linux kernel did not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allowed local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a 'mount -o remount' command within a user namespace. CVE-2014-1739: The media_device_enum_entities function in drivers/media/media-device.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call. CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel allowed local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket. CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allowed local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel, when SCTP authentication is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. CVE-2014-4171: mm/shmem.c in the Linux kernel did not properly implement the interaction between range notification and hole punching, which allowed local users to cause a denial of service (i_mutex hold) by using the mmap system call to access a hole, as demonstrated by interfering with intended shmem activity by blocking completion of (1) an MADV_REMOVE madvise call or (2) an FALLOC_FL_PUNCH_HOLE fallocate call. Also the following bugs were fixed : - KEYS: Fix stale key registration at error path (bnc#908163). - parport: parport_pc, do not remove parent devices early (bnc#856659). - xfs: fix directory hash ordering bug. - xfs: mark all internal workqueues as freezable (bnc#899785). - [media] uvc: Fix destruction order in uvc_delete() (bnc#897736). - cfq-iosched: Fix wrong children_weight calculation (bnc#893429). - target/rd: Refactor rd_build_device_space + rd_release_device_space (bnc#882639). - Btrfs: Fix memory corruption by ulist_add_merge() on 32bit arch (bnc#887046). - usb: pci-quirks: Prevent Sony VAIO t-series from switching usb ports (bnc#864375). - xhci: Switch only Intel Lynx Point-LP ports to EHCI on shutdown (bnc#864375). - xhci: Switch Intel Lynx Point ports to EHCI on shutdown (bnc#864375). - ALSA: hda - Fix broken PM due to incomplete i915 initialization (bnc#890114). - netbk: Don't destroy the netdev until the vif is shut down (bnc#881008). - swiotlb: don't assume PA 0 is invalid (bnc#865882). - PM / sleep: Fix request_firmware() error at resume (bnc#873790). - usbcore: don't log on consecutive debounce failures of the same port (bnc#818966).

    title Oracle Linux 7 : kernel (ELSA-2015-0290)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2014-0786.NASL
    description Updated kernel packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important) * A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important) * Use-after-free and information leak flaws were found in the way the Linux kernel's floppy driver processed the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use these flaws to escalate their privileges on the system. (CVE-2014-1737, CVE-2014-1738, Important) * It was found that the aio_read_events_ring() function of the Linux kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO ring head received from user space. A local, unprivileged user could use this flaw to disclose random parts of the (physical) memory belonging to the kernel and/or other processes. (CVE-2014-0206, Moderate) * An out-of-bounds memory access flaw was found in the Netlink Attribute extension of the Berkeley Packet Filter (BPF) interpreter functionality in the Linux kernel's networking implementation. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145, Moderate) * An information leak flaw was found in the way the skb_zerocopy() function copied socket buffers (skb) that are backed by user-space buffers (for example vhost-net and Xen netback), potentially allowing an attacker to read data from those buffers. (CVE-2014-2568, Low) Red Hat would like to thank Kees Cook of Google for reporting CVE-2014-3153 and Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. Google acknowledges Pinkie Pie as the original reporter of CVE-2014-3153. The CVE-2014-0206 issue was discovered by Mateusz Guzik of Red Hat. This update also fixes the following bugs : * Due to incorrect calculation of Tx statistics in the qlcninc driver, running the 'ethtool -S ethX' command could trigger memory corruption. As a consequence, running the sosreport tool, that uses this command, resulted in a kernel panic. The problem has been fixed by correcting the said statistics calculation. (BZ#1104972) * When an attempt to create a file on the GFS2 file system failed due to a file system quota violation, the relevant VFS inode was not completely uninitialized. This could result in a list corruption error. This update resolves this problem by correctly uninitializing the VFS inode in this situation. (BZ#1097407) * Due to a race condition in the kernel, the getcwd() system call could return '/' instead of the correct full path name when querying a path name of a file or directory. Paths returned in the '/proc' file system could also be incorrect. This problem was causing instability of various applications. The aforementioned race condition has been fixed and getcwd() now always returns the correct paths. (BZ#1099048) In addition, this update adds the following enhancements : * The kernel mutex code has been improved. The changes include improved queuing of the MCS spin locks, the MCS code optimization, introduction of the cancellable MCS spin locks, and improved handling of mutexes without wait locks. (BZ#1103631, BZ#1103629) * The handling of the Virtual Memory Area (VMA) cache and huge page faults has been improved. (BZ#1103630) 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.
