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 lt; 2.2.12 gt;= 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 "gt;=net-mail/cyrus-imapd-2.2.12"
