This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 8.04 LTS:
netpbm 2:10.0-11.1ubuntu0.1

Ubuntu 9.04:
netpbm 2:10.0-12ubuntu0.9.04.1

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

Details follow:

Marc Schoenefeld discovered a buffer overflow in Netpbm when loading certain images. If a user or automated system were tricked into opening a specially crafted XPM image, a remote attacker could crash Netpbm. The default compiler options for affected releases should reduce the vulnerability to a denial of service.
