Ubuntu Security Notice USN-304-1
26th June, 2006
gnupg vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
- Ubuntu 5.10
- Ubuntu 5.04
Details
Evgeny Legerov discovered that GnuPG did not sufficiently check overly
large user ID packets. Specially crafted user IDs caused a buffer
overflow. By tricking an user or remote automated system into
processing a malicous GnuPG message, an attacker could exploit this to
crash GnuPG or possibly even execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.06 LTS:
- gnupg 1.4.2.2-1ubuntu2.1
- Ubuntu 5.10:
- gnupg 1.4.1-1ubuntu1.3
- Ubuntu 5.04:
- gnupg 1.2.5-3ubuntu5.4
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system upgrade is sufficient to effect the
necessary changes.
