Updated php packages fix security vulnerability

Publication date: 17 Apr 2014
Modification date: 17 Apr 2014
Type: security
Affected Mageia releases : 3 , 4
CVE: CVE-2013-7345

Description

Updated php packages fix security vulnerability:

The BEGIN regular expression in the awk script detector in
magic/Magdir/commands in file before 5.15 uses multiple wildcards with
unlimited repetitions, which allows context-dependent attackers to cause a
denial of service (CPU consumption) via a crafted ASCII file that triggers a
large amount of backtracking, as demonstrated via a file with many newline
characters (CVE-2013-7345).

PHP contains a bundled copy of the file utility's libmagic library, so it was
vulnerable to this issue. It has been updated to versions 5.4.27 and 5.5.11,
which fix this issue and several other bugs.

Also, the timezonedb PHP PECL module has been updated to its newest version.

Additionally, php-apc has been rebuilt against the updated php packages.
