"This update for glibc fixes the following security issues :

  - CVE-2015-7547: A stack-based buffer overflow in
    getaddrinfo allowed remote attackers to cause a crash or
    execute arbitrary code via crafted and timed DNS
    responses (bsc#961721)

  - CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD
    environment variable allowed local attackers to bypass
    the pointer guarding protection of the dynamic loader on
    set-user-ID and set-group-ID programs (bsc#950944)

  - CVE-2015-8776: Out-of-range time values passed to the
    strftime function may cause it to crash, leading to a
    denial of service, or potentially disclosure information
    (bsc#962736)

  - CVE-2015-8778: Integer overflow in hcreate and hcreate_r
    could have caused an out-of-bound memory access. leading
    to application crashes or, potentially, arbitrary code
    execution (bsc#962737)

  - CVE-2014-9761: A stack overflow (unbounded alloca) could
    have caused applications which process long strings with
    the nan function to crash or, potentially, execute
    arbitrary code. (bsc#962738)

  - CVE-2015-8779: A stack overflow (unbounded alloca) in
    the catopen function could have caused applications
    which pass long strings to the catopen function to crash
    or, potentially execute arbitrary code. (bsc#962739)

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
