   An update that solves four vulnerabilities and has four
   fixes is now available.

Description:

   glibc has been updated to fix four security issues.

   These security issues were fixed:
   - CVE-2014-7817: The wordexp function in GNU C Library (aka glibc) 2.21
     did not enforce the WRDE_NOCMD flag, which allowed context-dependent
     attackers to execute arbitrary commands, as demonstrated by input
     containing "$((`...`))" (bnc#906371).
   - CVE-2015-1472: Heap buffer overflow in glibc swscanf (bnc#916222).
   - CVE-2014-9402: Denial of service in getnetbyname function (bnc#910599).
   - CVE-2013-7423: Getaddrinfo() writes DNS queries to random file
     descriptors under high load (bnc#915526).

   These non-security issues were fixed:
   - Fix infinite loop in check_pf (bsc#909053)
   - Restore warning about execution permission, it is still needed for
     noexec mounts (bsc#915985).
   - Don't touch user-controlled stdio locks in forked child (bsc#864081)
   - Don't use gcc extensions for non-gcc compilers (bsc#905313)
