USN-934-1: Netpbm vulnerability

29 April 2010

netpbm-free vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 9.10
  • Ubuntu 9.04
  • Ubuntu 8.04 LTS

Software Description

  • netpbm-free


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.
