kdegraphics security update
Security Advisory: Moderate
Updated kdegraphics packages that resolve multiple security issues in kfax
are now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team
The kdegraphics package contains graphics applications for the K Desktop
Environment.
During a source code audit, Chris Evans discovered a number of integer
overflow bugs that affect libtiff. The kfax application contains a copy of
the libtiff code used for parsing TIFF files and is therefore affected by
these bugs. An attacker who has the ability to trick a user into opening a
malicious TIFF file could cause kfax to crash or possibly execute arbitrary
code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2004-0886 and CAN-2004-0804 to these issues.
Additionally, a number of buffer overflow bugs that affect libtiff have
been found. The kfax application contains a copy of the libtiff code used
for parsing TIFF files and is therefore affected by these bugs. An attacker
who has the ability to trick a user into opening a malicious TIFF file
could cause kfax to crash or possibly execute arbitrary code. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0803 to this issue.
Users of kfax should upgrade to these updated packages, which contain
backported patches and are not vulnerable to this issue.
