Scientific Linux Security Update : cyrus-imapd on SL4.x, SL5.x, SL6.x i386/x86_64
High Nessus Plugin ID 61182
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThe cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and Sieve support.
An authentication bypass flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to read or post newsgroup messages on an NNTP server configured to require user authentication, without providing valid authentication credentials. (CVE-2011-3372)
A NULL pointer dereference flaw was found in the cyrus-imapd IMAP server, imapd. A remote attacker could send a specially crafted mail message to a victim that would possibly prevent them from accessing their mail normally, if they were using an IMAP client that relies on the server threading IMAP feature. (CVE-2011-3481)
Users of cyrus-imapd are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, cyrus-imapd will be restarted automatically.
SolutionUpdate the affected packages.
