 Mandriva Linux Security Advisory                         MDVSA-2014:073
 http://www.mandriva.com/en/support/security/

 Package : file
 Date    : April 9, 2014
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Updated file packages fix security vulnerabilities:
 
 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).
