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" References ========== [ 1 ] Cyrus IMAP Announcement http://asg.web.cmu.edu/archive/message.php?mailbox=archive.info-cyrus&msg=33723 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200502-29.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
