RedHat Linux An overflow exists in the article wrapping code for slrn.

                   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:  

1. Topic:

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

Red Hat Linux 7.0 - alpha, i386

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.

4. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh 

where  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.Red for more info):

6. RPMs required:

Red Hat Linux 6.2:





Red Hat Linux 7.0:

tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg
