3. Problem description:
An integer overflow flaw was found in libXpm, which is used by some
applications for loading of XPM images. An attacker 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.
Several integer overflow bugs were found in the way XFree86 parses
pixmap images. It is possible for a user to gain elevated privileges by
loading a specially crafted pixmap image. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-2495 to
Users of XFree86 should upgrade to these updated packages, which contain
backported patches and are not vulnerable to these issues.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.
Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
