Description Jan Lieskovsky 2010-10-05 14:24:35 EDT

A security flaw was found in the way Dovecot IMAP server
updated own Access Control List (ACL) cache for rules
specifying user rights on mailboxes stored in the private
namespace of the particular user. A local attacker could
use this flaw to prevent the mailbox administrator to restrict
the ACL rule via a symlink attack on the shared mailbox.
