Debian Security Advisory DSA-3024-1 [email protected]
http://www.debian.org/security/ Thijs Kinkhorst

Package : gnupg
CVE ID : CVE-2014-5270
Debian Bug : 725411

Genkin, Pipman and Tromer discovered a side-channel attack on Elgamal
encryption subkeys (CVE-2014-5270).

In addition, this update hardens GnuPG's behaviour when treating
keyserver responses; GnuPG now filters keyserver responses to only
accepts those keyid's actually requested by the user.

For the stable distribution (wheezy), this problem has been fixed in
version 1.4.12-7+deb7u6.

For the testing (jessie) and unstable distribution (sid), this
problem has been fixed in version 1.4.18-4.

We recommend that you upgrade your gnupg packages.
