This security upload has been prepared in cooperation of the Debian Kernel, Security and LTS Teams and features the upstream stable release 2.6.32.64 (see https://lkml.org/lkml/2014/11/23/181 for more information for that). It fixes the CVEs described below.

Note: if you are using the openvz flavors, please consider three things: a.) we haven't got any feedback on them (while we have for all other flavors) b.) so do your test before deploying them and c.) once you have done so, please give feedback to debian-lts@lists.debian.org. 

If you are not using openvz flavors, please still consider b+c :-)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5936 advisory.

    - USB: serial: omninet: fix reference leaks at open (Johan Hovold)  [Orabug: 30484765]  {CVE-2017-8925}
    - x86_32, entry: Store badsys error code in %eax (Sven Wegener)  [Orabug: 30783266]  {CVE-2014-4508}     {CVE-2014-4508}

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001838 advisory.

    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.

The Linux Kernel was updated to fix various bugs and security issues.

CVE-2014-4699: The Linux kernel on Intel processors did not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allowed local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls.

CVE-2014-4667: The sctp_association_free function in net/sctp/associola.c in the Linux kernel did not properly manage a certain backlog value, which allowed remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet.

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.

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-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function.

CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not properly maintain the user_ctl_count value, which allowed local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls.

CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allowed local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call.

CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel did not ensure possession of a read/write lock, which allowed local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

CVE-2014-4652: Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

CVE-2014-4014: The capabilities implementation in the Linux kernel did not properly consider that namespaces are inapplicable to inodes, which allowed 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.

CVE-2014-2309: The ip6_route_add function in net/ipv6/route.c in the Linux kernel did not properly count the addition of routes, which allowed remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets.

CVE-2014-3917: kernel/auditsc.c in the Linux kernel, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allowed local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number.

CVE-2014-0131: Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel allowed attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation.

CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel did not check whether a certain length value is sufficiently large, which allowed local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions.

CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel used the reverse order in a certain subtraction, which allowed local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the
__skb_get_nlattr_nest function before the vulnerability was announced.

Additional Bug fixed :

  - HID: logitech-dj: Fix USB 3.0 issue (bnc#788080).

The 3.14.9 stable update contains a number of important fixes across the tree.
