CLA-2002:487-imap

by Nikola Strahija on May 25th, 2002 "imap"[4] is a package that contains POP2, POP3 and IMAP servers developed at the University of Washington (UW). Marcell Fodor published[1] a remote buffer overflow vulnerability[2][3] in the IMAP server. This vulnerability can be exploited by a remote attacker after he or she has been successfully authenticated by the server. Arbitrary code could then be executed, but with the privileges of the authenticated user. This vulnerability only affects the IMAP server available in this package. The updated packages have been fixed with the patch made available by the author[5].


SOLUTION
It is recommended that all imap users upgrade their packages.

After the upgrade, no restart is necessary since these servers are
handled by inetd or xinetd.
