Red Hat, Inc. Red Hat Security Advisory Synopsis: buffer overflow in slrn Advisory ID: RHSA-2001:028-02 Issue date: 2001-03-09 Updated on: 2001-03-13 Product: Red Hat Linux Keywords: slrn wrap overflow Cross references: Obsoletes:
An overflow exists in the slrn pacakge as shipped in Red Hat Linux 7 and Red Hat Linux 6.x, which could possibly lead to remote users executing arbitrary code as the user running slrn.
It is recommended that all users of slrn update to the fixed packages. Users of Red Hat Linux 6.0 or 6.1 should use the packages for Red Hat Linux 6.2.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc
3. Problem description:
An overflow exists in the article wrapping code for slrn. By posting a carefully constructed article, it would be theoretically possible for a remote user to execute arbitrary code as the user running slrn.
No know *exploits* of this overflow have been reported, but articles that will cause slrn to crash do exist.
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 directly *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
6. RPMs required:
Red Hat Linux 6.2:
Red Hat Linux 7.0:
