Security update for Linux kernel

SUSE Security Update: Security update for Linux kernel
Announcement ID: SUSE-SU-2014:1698-1
Rating: important
References: #907818 #909077 #910251
Affected Products:
  • SUSE Linux Enterprise Server 11 SP2 LTSS
  • SUSE Linux Enterprise Server 11 SP1 LTSS
  • SLE 11 SERVER Unsupported Extras

  • An update that fixes three vulnerabilities is now available. It includes two new package versions.


    The SUSE Linux Enterprise 11 Service Pack 2 LTSS kernel has been updated
    to fix security issues on kernels on the x86_64 architecture.

    The following security bugs have been fixed:


    CVE-2014-9322: A local privilege escalation in the x86_64 32bit
    compatibility signal handling was fixed, which could have been used by
    local attackers to crash the machine or execute code.


    CVE-2014-9090: The do_double_fault function in
    arch/x86/kernel/traps.c in the Linux kernel did not properly handle faults
    associated with the Stack Segment (SS) segment register, which allowed
    local users to cause a denial of service (panic) via a modify_ldt system
    call, as demonstrated by sigreturn_32 in the 1
    -clock-tests test suite.


    CVE-2014-8133: Insufficient validation of TLS register usage could
    have leaked information from the kernel stack to userspace.

    Security Issues:

    * CVE-2014-8133

    * CVE-2014-9090

    * CVE-2014-9322


    Everyone using the Linux Kernel on x86_64 architecture should update.
