Fedora Legacy Update Advisory

Synopsis: Updated cvs package fixes security issues
Advisory ID: FLSA:155508
Issue date: 2005-05-12
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2005-0753
---------------------------------------------------------------------


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

An updated cvs package that fixes security bugs is now available.

CVS (Concurrent Version System) is a version control system.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386

3. Problem description:

A buffer overflow bug was found in the way the CVS client processes version and author information. If a user can be tricked into connecting to a malicious CVS server, an attacker could execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0753 to this issue.

All users of cvs should upgrade to this updated package, which includes a backported patch to correct these issues.

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.
