USN-332-1: gnupg vulnerability

Releases

• Ubuntu 6.06
• Ubuntu 5.10
• Ubuntu 5.04

Details

Evgeny Legerov discovered that gnupg did not sufficiently check the
validity of the comment and a control field. Specially crafted GPG
data could cause a buffer overflow. This could be exploited to execute
arbitrary code with the user's privileges if an attacker can trick an
user into processing a malicious encrypted/signed document with gnupg.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.06

• gnupg - 1.4.2.2-1ubuntu2.2

Ubuntu 5.10

• gnupg - 1.4.1-1ubuntu1.4

Ubuntu 5.04

• gnupg - 1.2.5-3ubuntu5.5

In general, a standard system upgrade is sufficient to effect the
necessary changes.
