Affected Products:
  • SUSE Linux Enterprise Workstation Extension 12-SP1
  • SUSE Linux Enterprise Software Development Kit 12-SP1
  • SUSE Linux Enterprise Server 12-SP1
  • SUSE Linux Enterprise Module for Public Cloud 12

  • An update that fixes three vulnerabilities is now available.

    Description:


    The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
    critical security fixes.

    The following security bugs were fixed:

    - CVE-2016-8655: A race condition in the af_packet packet_set_ring
    function could be used by local attackers to crash the kernel or gain
    privileges (bsc#1012754).
    - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the
    Linux kernel did not validate the relationship between the minimum
    fragment length and the maximum packet size, which allowed local users
    to gain privileges or cause a denial of service (heap-based buffer
    overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).
    - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in
    the Linux kernel lacks chunk-length checking for the first chunk, which
    allowed remote attackers to cause a denial of service (out-of-bounds
    slab access) or possibly have unspecified other impact via crafted SCTP
    data (bnc#1011685).
