Release Notes: Addition of the LAYER tag to HTML defanging (primarily of interest to people running Webmail programs), modifications to the Office Macro scanner, and fixes for ignoring some code used in default-template infector macros, and genration of some false positives. The sanitizer recurses into multipart attachments in addition to RFC822 attachments; the only hole left now is defanging BASE64-encoded HTML attachments. If a file attachment does not have a filename specified, a default filename will be provided.
Release Notes: This release added default poisoning of the application/x-msdownload MIME type in response to a new worm. Full MIME-type poisoning support will be available shortly. This release was accelerated for security reasons.
Release Notes: The unrar executable check was fixed to not test for unrar if RAR scanning is already explicitly disabled by $DISABLE_RAR_SCAN. Recipient notification now works when sanitizing on a relay (e.g. in front of an Exchange server).
Release Notes: RAR archive scanning and the ability to mangle or poison WMF image files were added.
Release Notes: This release fixes bugs in scanning of multi-layered MIME attachments, and an infinite loop on certain MIME boundary strings.
Release Notes: Scanning of JPEG attachments to detect Microsoft BO attempts was added. A minor bugfix was made in .ZIP and document scanning.
