The evolution-data-server package provides a unified backend for programs
that work with contacts, tasks, and calendar information.
A flaw was found in the way evolution-data-server processes certain IMAP
server messages. If a user can be tricked into connecting to a malicious
IMAP server it may be possible to execute arbitrary code as the user
running the evolution-data-server process. (CVE-2007-3257)
All users of evolution-data-server should upgrade to these updated
packages, which contain a backported patch which resolves this issue.
