USN-304-1: gnupg vulnerability

27 June 2006

gnupg vulnerability



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 versions:

Ubuntu 6.06
  • gnupg -
Ubuntu 5.10
  • gnupg - 1.4.1-1ubuntu1.3
Ubuntu 5.04
  • gnupg - 1.2.5-3ubuntu5.4

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