Updated Emacs packages that fix a string format issue are now available.
Emacs is a powerful, customizable, self-documenting, modeless text editor.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386
3. Problem description:
Max Vozeler discovered several format string vulnerabilities in the movemail utility of Emacs. If a user connects to a malicious POP server, an attacker can execute arbitrary code as the user running emacs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0100 to this issue.
Users of Emacs are advised to upgrade to these updated packages, which contain backported patches to correct this issue.
4. Solution:
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:
yum update
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. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get.
