Cyrus IMAP pop3d buffer overflow
|cyrus-imap-pop3d-bo (26578)||High Risk|
Cyrus IMAP Server is vulnerable to a buffer overflow in the imap/pop3d.c module when the "popsubfolders" option is enabled. By sending an overly long USER command to the pop3 daemon, a remote attacker could overflow a buffer and execute arbitrary commands on the system.
Upgrade to the latest version of Cyrus IMAP (2.3.4 or later), available from the Cyrus IMAP Web site. See References.
