DESCRIPTION
cyrus-imapd[1] is an IMAP and POP3 mail server with several advanced
features such as SASL authentication, server-side mail filtering,
mailbox ACLs and others.

Multiple buffer overflows[2] in Cyrus IMAPd before 2.2.11 may allow
attackers to execute arbitrary code via an off-by-one error in the
imapd annotate extension, an off-by-one error in cached header
handling a stack-based buffer overflow in fetchnews, or a stack-based
buffer overflow in imapd.

SOLUTION
It is recommended that all cyrus-imapd users upgrade their packages.
The service will be automatically restarted after the upgrade if
needed.
