USN-26-1: bogofilter vulnerability

Publication date

17 November 2004

Overview

bogofilter vulnerability

Releases

Details

Antti-Juhani Kaijanaho discovered a Denial of Service vulnerability in
bogofilter. The quoted-printable decoder handled certain Base-64
encoded strings in an invalid way which caused a buffer overflow and
an immediate program abort.

The exact impact depends on the way bogofilter is integrated into the
system. In common setups, the mail that contains such malformed
headers is deferred by the mail delivery agent and remains in the
queue, where it will eventually bounce back to the sender.
