 Mandriva Linux Security Advisory                         MDVSA-2013:247
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : gnupg
 Date    : October 10, 2013
 Affected: Business Server 1.0, Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in gnupg:
 
 GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with
 all bits cleared (no usage permitted) as if it has all bits set
 (all usage permitted), which might allow remote attackers to bypass
 intended cryptographic protection mechanisms by leveraging the subkey
 (CVE-2013-4351).
 
 Special crafted input data may be used to cause a denial of service
 against GPG. GPG can be forced to recursively parse certain parts of
 OpenPGP messages ad infinitum (CVE-2013-4402).
 
 The updated packages have been patched to correct this issue.
