Mandriva Linux Security Advisory : glibc (MDVSA-2014:152)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated glibc packages fix security issues :

Stephane Chazelas discovered that directory traversal issue in locale
handling in glibc. glibc accepts relative paths with .. components in
the LC_* and LANG variables. Together with typical OpenSSH
configurations (with suitable AcceptEnv settings in sshd_config), this
could conceivably be used to bypass ForceCommand restrictions (or
restricted shells), assuming the attacker has sufficient level of
access to a file system location on the host to create crafted locale
definitions there (CVE-2014-0475).

David Reid, Glyph Lefkowitz, and Alex Gaynor discovered a bug where
posix_spawn_file_actions_addopen fails to copy the path argument
(glibc bz #17048) which can, in conjunction with many common memory
management techniques from an application, lead to a use after free,
or other vulnerabilities (CVE-2014-4043).
