"This glibc update fixes a critical privilege escalation problem and
two additional issues :

  - bnc#892073: An off-by-one error leading to a heap-based
    buffer overflow was found in __gconv_translit_find(). An
    exploit that targets the problem is publicly available.
    (CVE-2014-5119)

  - bnc#836746: Avoid race between {, __de}allocate_stack
    and __reclaim_stacks during fork.

  - bnc#844309: Fixed various overflows, reading large
    /etc/hosts or long names. (CVE-2013-4357)

  - bnc#894553, bnc#894556: Fixed various crashes on invalid
    input in IBM gconv modules. (CVE-2014-6040,
    CVE-2012-6656)

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."
