GLSA-200411-34 : Cyrus IMAP Server: Multiple remote vulnerabilities
Critical Nessus Plugin ID 15833
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200411-34 (Cyrus IMAP Server: Multiple remote vulnerabilities)
Multiple vulnerabilities have been discovered in the argument parsers of the 'partial' and 'fetch' commands of the Cyrus IMAP Server (CAN-2004-1012, CAN-2004-1013). There are also buffer overflows in the 'imap magic plus' code that are vulnerable to exploitation as well (CAN-2004-1011, CAN-2004-1015).
An attacker can exploit these vulnerabilities to execute arbitrary code with the rights of the user running the Cyrus IMAP Server.
There is no known workaround at this time.
SolutionAll Cyrus-IMAP Server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/cyrus-imapd-2.2.10'
