 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.
