Ubuntu Security Notice USN-26-1 November 17, 2004
bogofilter vulnerability
CAN-2004-1007
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
The following packages are affected:
bogofilter
The problem can be corrected by upgrading the affected package to
version 0.92.0-1ubuntu0.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.
Details follow:
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.
