Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : libgcrypt11 vulnerability (USN-2339-2)

Low Nessus Plugin ID 77527


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


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.


Update the affected libgcrypt11 package.
