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.
