REDHAT-BUG-495892
First published: Wed Apr 15 2009(Updated: )
An invalid free() flaw was found in xpdf's JBIG2 decoder. If a malicious PDF file could free() attacker controlled data, it may be possible to execute arbitrary code with the permissions of the user running xpdf. Will Dormann of the CERT/CC created the extensive testsuite for the JBIG2 decoder in various PDF libraries that found this flaw. Acknowledgements: Red Hat would like to thank Will Dormann of the CERT/CC for responsibly reporting this flaw.
