Ubuntu Security Notice USN-26-1
17th November, 2004
bogofilter vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- bogofilter
