Description Mark J. Cox 2005-07-21 13:13:46 UTC

It's likely this will be completely caught by FC4 FORTIFY_SOURCE however I've
not verified it yet.  See RHEL bug for (private) proof of concept.

+++ This bug was initially created as a clone of Bug #163816 +++

We were alerted today to a Debian bug report showing a flaw where a malicious
POP3 server could overflow a stack buffer in fetchmail.

Draft advisory at http://fetchmail.berlios.de/fetchmail-SA-2005-01.txt

(Actually it isn't and wouldn't be caught by FORTIFY_SOURCE)

Comment 2 Miloslav Trmač 2005-07-22 08:08:51 UTC

Fixed in fetchmail-6.2.5-7.fc[34].1
