Package        : libgcrypt11
Vulnerability  : information leak
Problem type   : local
Debian-specific: no
CVE ID         : CVE-2013-4242

Yarom and Falkner discovered that RSA secret keys in applications using
the libgcrypt11 library, for example GnuPG 2.x, could be leaked via
a side channel attack, where a malicious local user could obtain private
key information from another user on the system.

For the oldstable distribution (squeeze), this problem has been fixed in
version 1.4.5-2+squeeze1.

For the stable distribution (wheezy), this problem has been fixed in
version 1.5.0-5+deb7u1.

For the testing distribution (jessie) and unstable distribution (sid),
this problem has been fixed in version 1.5.3-1.

We recommend that you upgrade your libgcrypt11 packages.
