1. Systems affected:

All KDE 3.2.x releases, KDE 3.3.0 and KDE 3.3.1.

2. Overview:

Chris Evans notified the KDE security team about multiple integer overflow and integer arithmetic flaws in xpdf 3.0.

These flaws, if exploited, can cause xpdf (and therefore kpdf) to hang using 100% CPU, crash the viewer or corrupt the program heap. It might be possible to execute arbitrary code. The Common Vulnerabilities and Exposures project assigned CAN-2004-0889 to this issue.

kpdf, the KDE pdf viewer, shares code with xpdf 2.02. This code is significantly different from the xpdf 3.0 codebase, but is also affected by similiar issues. Sebastian Krahmer from the SUSE security team developed a patch that corrects integer overflows in the XRef code. This patch is made available below for kpdf as shipped in the KDE 3.2.x releases. The Common Vulnerabilities and Exposures project assigned CAN-2004-0888 to this issue.

KDE 3.3.1 contains a kpdf based on xpdf 3.0. We're providing a patch to fix the remaining integer overflows in this code base.
