----------------------------------------------------------------------
Red Hat Security Advisory

Synopsis: Important: kdegraphics security update
Advisory ID: RHSA-2005:066-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-066.html
Issue date: 2005-02-15
Updated on: 2005-02-15
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-0888 CAN-2004-1125 CAN-2005-0064
----------------------------------------------------------------------

1. Summary:

Updated kdegraphics packages that resolve security issues in kpdf are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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.
