Ubuntu 14.04 LTS / 16.04 LTS : gnupg vulnerability (USN-3733-1)

Medium Nessus Plugin ID 111581


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


Daniel J. Bernstein, Joachim Breitner, Daniel Genkin, Leon Groot Bruinderink, Nadia Heninger, Tanja Lange, Christine van Vredendaal, and Yuval Yarom discovered that GnuPG is vulnerable to a cache side-channel attack. A local attacker could use this attack to recover RSA 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 gnupg, gnupg-curl and / or gpgv packages.
