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.
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.
