http://secunia.com/advisories/16176/

CRITICAL:
Moderately critical

IMPACT:
System access

>From remote

SOFTWARE:
Fetchmail 6.x

DESCRIPTION:
Matthias Andree has reported a vulnerability in fetchmail, which can
be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error when handling
UIDL responses from a POP3 server and can be exploited to cause a
stack-based buffer overflow.

Successful exploitation allows execution of arbitrary code, but
requires that the user is tricked into connecting to a malicious POP3
server.

The vulnerability has been reported in versions 6.2.0, 6.2.5, and
6.2.5.1. Prior versions may also be affected.

SOLUTION:
Update to version 6.2.5.2 or later.
