An update that solves four vulnerabilities and has four security fixes can now be installed.

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)
