 Mandriva Linux Security Advisory                         MDVSA-2014:152
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : glibc
 Date    : August 6, 2014
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem 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).
