Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
