1. Systems affected:
kdelibs as shipped with KDE 3.2 up to including KDE 3.4.
2. Overview:
kimgio contains a PCX image file format reader that does not properly perform input validation. A source code audit performed by the KDE security team discovered several vulnerabilities in the PCX and other image file format readers, some of them exploitable to execute arbitrary code.
3. Impact:
Remotly supplied, specially crafted image files can be used to execute arbitrary code.
4. Solution:
Source code patches have been made available which fix these vulnerabilities. Contact your OS vendor / binary package provider for information about how to obtain updated binary packages.
5. Patch:
A patch for KDE 3.4.0 is available from
