RHSA-2005:393 - Security Advisory

Topic

Updated kdelibs packages that fix a flaw in kimgio input validation are now
available for Red Hat Enterprise Linux 4.

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

Description

KDE is a graphical desktop environment for the X Window System. Konqueror
is the file manager for the K Desktop Environment.

A source code audit performed by the KDE security team discovered several
vulnerabilities in the PCX and other image file format readers.

A buffer overflow was found in the kimgio library for KDE 3.4.0. An
attacker could create a carefully crafted PCX image in such a way that it
would cause kimgio to execute arbitrary code when processing the image.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-1046 to this issue.

All users of kdelibs should upgrade to these updated packages, which
contain a backported security patch to correct these issues.
