DESCRIPTION
 "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.
