imlib2 vulnerabilities

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

  • Ubuntu 6.10
  • Ubuntu 6.06 LTS
  • Ubuntu 5.10

Software Description


M. Joonas Pihlaja discovered that imlib2 did not sufficiently verify the validity of ARGB, JPG, LBM, PNG, PNM, TGA, and TIFF images. If a user were tricked into viewing or processing a specially crafted image with an application that uses imlib2, the flaws could be exploited to execute arbitrary code with the user’s privileges.

Update instructions

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

Ubuntu 6.10
libimlib2 - 1.2.1-2ubuntu1.1
Ubuntu 6.06 LTS
libimlib2 - 1.2.1-2ubuntu0.1
Ubuntu 5.10
libimlib2 - 1.2.0-2.2ubuntu2.1

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