Description

This module triggers an off-by-two overflow in the
rsyslog daemon. This flaw is unlikely to yield code execution
but is effective at shutting down a remote log daemon. This bug
was introduced in version 4.6.0 and corrected in 4.6.8/5.8.5.
Compiler differences may prevent this bug from causing any
noticeable result on many systems (RHEL6 is affected).
