CLA-2002-03-28-Potential vulnerabilities in imlib

by Nikola Strahija on April 1st, 2002 Alan Cox discovered some situations where a heap corruption[1] may occur when processing some malformed image. Al Viro found that imlib was falling back to the NetPBM library[2] when processing some kind of images, but NetPBM is not suitable to process untrusted image input.


An attacker could use a crafted image to exploit a program linked to
imlib (like a mailer program or an image viewer) and cause a DoS or
even remote code execution.

This update to imlib 1.9.13 solves both problems.


SOLUTION
All users of imlib should do the upgrade. Notice that the
vulnerabilities can be exploited through programs linked to imlib
(like the Electronic Eyes image viewer), so you should restart them
in order to load the updated imlib.
