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."
