Fedora Legacy Update Advisory

Synopsis: Updated emacs packages fix a security issue
Advisory ID: FLSA:152898
Issue date: 2006-05-12
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2005-0100
---------------------------------------------------------------------



---------------------------------------------------------------------
1. Topic:

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.
