Ubuntu 14.04 LTS : Libgcrypt vulnerability (USN-2339-2)

high Nessus Plugin ID 77527

Synopsis

The remote Ubuntu host is missing a security update.

Description

Daniel Genkin, Adi Shamir, and Eran Tromer discovered that Libgcrypt was susceptible to an adaptive chosen ciphertext attack via physical side channels. 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.

Solution

Update the affected libgcrypt11, libgcrypt11-dev and / or libgcrypt11-udeb packages.
