Detailed Explanation for this Vulnerability Assessment
Updated XFree86 packages that fix a libXpm integer overflow flaw are now
This update has been rated as having moderate security impact by the Red Hat
Security Response Team.
XFree86 is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces (GUIs) such as GNOME and KDE are designed upon.
An integer overflow flaw was found in libXpm, which is used by some
applications for loading of XPM images. A possible hacker could create a
malicious XPM file that would execute arbitrary code if opened by a victim
using an application linked to the vulnerable library. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-2005-0605 to this issue.
The updated XFree86 packages also address the following minor issues:
- Updated XFree86-4.3.0-keyboard-disable-ioport-access-v3.patch to make
warning messages less alarmist.
- Backported XFree86-4.3.0-libX11-stack-overflow.patch from xorg-x11-6.8.1
packaging to fix stack overflow in libX11, which was discovered by new
security features of gcc4.
Users of XFree86 should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
