Fedora Legacy Update AdvisorySynopsis: Updated gaim package resolves security issues Advisory ID: FLSA:2188 Issue date: 2005-02-10 Product: Red Hat Linux, Fedora Core Keywords: Bugfix Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2188 CVE Names: CAN-2004-0891 ---------------------------------------------------------------------
--------------------------------------------------------------------- 1. Topic:
An updated gaim package that fixes security issues and various bugs is now avaliable.
The gaim application is a multi-protocol instant messaging client.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386
3. Problem description:
A buffer overflow has been discovered in the MSN protocol handler. When receiving unexpected sequence of MSNSLP messages, it is possible that an attacker could cause an internal buffer overflow, leading to a crash or possible code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0891 to this issue.
This updated gaim package also fixes multiple user interface, protocol, and error handling problems, including an ICQ communication encoding issue.
Users of gaim are advised to upgrade to this updated package which contains gaim version 1.0.2 and is not vulnerable to 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.
