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:

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.
