"Recently another buffer overflow has been discovered in the SASL
authentication module of the Cyrus IMAP server. An off-by-one
comparison error in the mysasl_canon_user() function could lead to a
missing termination of an user name string.

This vulnerability could allow remote, attacker-supplied machine code
to be executed in the context of the affected server process. Since
the IMAP server usually runs as unprivileged user 'cyrus', there is no
possibility of root privilege escalation.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
