Mandriva Linux Security Advisory : gnupg (MDVSA-2013:247)

This script is Copyright (C) 2013 Tenable Network Security, Inc.

Synopsis :

The remote Mandriva Linux host is missing one or more security

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

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.
