Mandriva Linux Security Advisory MDVSA-2013:205
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : gnupg
Date : August 1, 2013
Affected: Business Server 1.0, Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

A vulnerability has been discovered and corrected in gnupg and in
libgcrypt:

Yarom and Falkner discovered that RSA secret keys in applications
using GnuPG 1.x, and using the libgcrypt library, could be leaked via a
side channel attack, where a malicious local user could obtain private
key information from another user on the system (CVE-2013-4242).

The updated packages have been patched to correct this issue.
