SUSE SLED12 / SLES12 Security Update : glibc (SUSE-SU-2015:0526-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

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)

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.
