Ximian Evolution Mail User Agent 1.2.2 and earlier allows remote attackers to cause a denial of service (memory consumption) via a mail message that is uuencoded multiple times.

The handle_image function in mail-format.c for Ximian Evolution Mail User Agent 1.2.2 and earlier does not properly escape HTML characters, which allows remote attackers to inject arbitrary data and HTML via a MIME Content-ID header in a MIME-encoded image.
