========================================================================== Ubuntu Security Notice USN-2554-1 April 01, 2015
gnupg, gnupg2 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in GnuPG.
Software Description: - gnupg: GNU privacy guard - a free PGP replacement - gnupg2: GNU privacy guard - a free PGP replacement
Details:
Daniel Genkin, Lev Pachmanov, Itamar Pipman, and Eran Tromer discovered that GnuPG was susceptible to an attack via physical side channels. A local attacker could use this attack to possibly recover private keys. (CVE-2014-3591)
Daniel Genkin, Adi Shamir, and Eran Tromer discovered that GnuPG was susceptible to an attack via physical side channels. A local attacker could use this attack to possibly recover private keys. (CVE-2015-0837)
Hanno Böck discovered that GnuPG incorrectly handled certain malformed keyrings. If a user or automated system were tricked into opening a malformed keyring, a remote attacker could use this issue to cause GnuPG to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-1606, CVE-2015-1607)
In addition, this update improves GnuPG security by validating that the keys returned by keyservers match those requested.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.10: gnupg 1.4.16-1.2ubuntu1.2 gnupg2 2.0.24-1ubuntu2.2
Ubuntu 14.04 LTS: gnupg 1.4.16-1ubuntu2.3 gnupg2 2.0.22-3ubuntu1.3
Ubuntu 12.04 LTS: gnupg 1.4.11-3ubuntu2.9 gnupg2 2.0.17-2ubuntu2.12.04.6
Ubuntu 10.04 LTS: gnupg 1.4.10-2ubuntu1.8
In general, a standard system update will make all the necessary changes.
