Synopsis
========
The Cyrus IMAP Server is affected by several overflow vulnerabilities
which could potentially lead to the remote execution of arbitrary
code.
Background
==========
The Cyrus IMAP Server is an efficient, highly-scalable IMAP e-mail
server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-mail/cyrus-imapd < 2.2.12 >= 2.2.12
Description
===========
Possible single byte overflows have been found in the imapd annotate
extension and mailbox handling code. Furthermore stack buffer overflows
have been found in fetchnews, the backend and imapd.
Impact
======
An attacker, who could be an authenticated user or an admin of a
peering news server, could exploit these vulnerabilities to execute
arbitrary code with the rights of the user running the Cyrus IMAP
Server.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Cyrus IMAP Server users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/cyrus-imapd-2.2.12"
