RHSA-2011:0859-01 -- Redhat cyrus-imapd

ID: oval:org.secpod.oval:def:500170Date: (C)2012-01-31   (M)2021-09-11
Class: PATCHFamily: unix




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. 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.
