Heap-based buffer overflow in the progressive PNG Image loader (decoders/pngloader.cpp) in KHTML in KDE 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted image.

A heap overflow in the PNG loader of KHTML has been fixed.
CVE-2008-1670 has been assigned to this issue.

The remote Fedora host is missing one or more security updates :
