(RHSA-2005:066) kdegraphics security update

The kdegraphics packages contain applications for the K Desktop Environment
including kpdf, a pdf file viewer.

A buffer overflow flaw was found in the Gfx::doImage function of Xpdf that
also affects kpdf due to a shared codebase. An attacker could construct a
carefully crafted PDF file that could cause kpdf to crash or possibly
execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-1125 to
this issue.

A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of
Xpdf which also affects kpdf due to a shared codebase. An attacker could
construct a carefully crafted PDF file that could cause kpdf to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0064 to
this issue.

During a source code audit, Chris Evans and others discovered a number of
integer overflow bugs that affected all versions of Xpdf which also affects
kpdf due to a shared codebase. An attacker could construct a carefully
crafted PDF file that could cause kpdf to crash or possibly execute
arbitrary code when opened. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-0888 to this issue.

Users should update to these erratum packages which contain backported
patches to correct these issues.
