Ubuntu Security Notice USN-2339-1
September 03, 2014

gnupg vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 12.04 LTS
– Ubuntu 10.04 LTS

Summary:

GnuPG could expose sensitive information when performing decryption.

Software Description:
– gnupg: GNU privacy guard – a free PGP replacement

Details:

Daniel Genkin, Adi Shamir, and Eran Tromer discovered that GnuPG was
susceptible to an adaptive chosen ciphertext attack via physical side
channels. A local attacker could use this attack to possibly recover
private keys.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
gnupg 1.4.11-3ubuntu2.7

Ubuntu 10.04 LTS:
gnupg 1.4.10-2ubuntu1.7

In general, a standard system update will make all the necessary changes.
