Ubuntu 4.10 : bogofilter vulnerability (USN-26-1)

Medium Nessus Plugin ID 20641


The remote Ubuntu host is missing a security-related patch.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected bogofilter package.
