========================================================================== Ubuntu Security Notice USN-1570-1 September 17, 2012
gnupg, gnupg2 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS
Summary:
GnuPG could be tricked into downloading a different key when downloading from a key server.
Software Description: - gnupg: GNU privacy guard - a free PGP replacement - gnupg2: GNU privacy guard - a free PGP replacement
Details:
It was discovered that GnuPG used a short ID when downloading keys from a keyserver, even if a long ID was requested. An attacker could possibly use this to return a different key with a duplicate short key id.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: gnupg 1.4.11-3ubuntu2.1 gnupg2 2.0.17-2ubuntu2.12.04.1
Ubuntu 11.10: gnupg 1.4.11-3ubuntu1.11.10.1 gnupg2 2.0.17-2ubuntu2.11.10.1
Ubuntu 11.04: gnupg 1.4.11-3ubuntu1.11.04.1 gnupg2 2.0.14-2ubuntu1.2
Ubuntu 10.04 LTS: gnupg 1.4.10-2ubuntu1.1 gnupg2 2.0.14-1ubuntu1.4
Ubuntu 8.04 LTS: gnupg 1.4.6-2ubuntu5.1 gnupg2 2.0.7-1ubuntu0.2
In general, a standard system update will make all the necessary changes.
