Ubuntu 12.04 LTS / 14.04 LTS / 15.10 : libgcrypt11, libgcrypt20 vulnerability (USN-2896-1)

Low Nessus Plugin ID 88747


The remote Ubuntu host is missing one or more security-related patches.


Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer discovered that Libgcrypt was susceptible to an 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 and / or libgcrypt20 packages.
