Caldera International, Inc. Security Advisory
Subject: Linux: imlib processes untrusted images
Advisory number: CSSA-2002-019.0
Issue date: 2002 April 29
Cross reference:
____________________________________________________________________________
1. Problem Description
Imlib versions prior to 1.9.13 would fall back to loading images
via the NetPBM package. NetPBM has various problems itself
that make it unsuitable for loading untrusted images. This
may allow attackers to construct images that, when loaded by
a viewer using Imlib, could cause crashes or potentially, the
execution of arbitrary code.
In addition, this version (1.9.14) also includes some further
fixes from the imlib team.
2. Vulnerable Supported Versions
