Wolfram Kleff found a problem in fetchmail: it would crash when processing emails with extremely long headers. The problem was a buffer overflow in the header parser which could be exploited. This has been fixed in version 5.3.3-1.2, and we recommend that you upgrade your fetchmail package immediately.
