The folks at F-Secure issued a bulletin today highlighting a buffer overflow in the web console feature of F-Secure Anti-Virus for Microsoft Exchange and F-Secure Internet Gatekeeper.  F-Secure rates this vulnerability as high in the cases where the web console is configured to only allow connections from localhost or specific trusted hosts and critical if configured to allow connections from all hosts.  They have released patches, the table below is taken directly from their advisory.
