Title:	RedHat Update for cyrus-imapd RHSA-2011:0859-01
Summary:	The remote host is missing an update for the 'cyrus-imapd'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'cyrus-imapd' package(s) announced via the referenced advisory. Vulnerability Insight: The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and Sieve support. It was discovered that cyrus-imapd did not flush the received commands buffer after switching to TLS encryption for IMAP, LMTP, NNTP, and POP3 sessions. A man-in-the-middle attacker could use this flaw to inject protocol commands into a victim's TLS session initialization messages. This could lead to those commands being processed by cyrus-imapd, potentially allowing the attacker to steal the victim's mail or authentication credentials. (CVE-2011-1926) Users of cyrus-imapd are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, cyrus-imapd will be restarted automatically. Affected Software/OS: cyrus-imapd on Red Hat Enterprise Linux (v. 5 server), Red Hat Enterprise Linux AS version 4, Red Hat Enterprise Linux ES version 4, Red Hat Enterprise Linux WS version 4 Solution: Please Install the Updated Packages. CVSS Score: 5.1 CVSS Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
