Title:RedHat Security Advisory RHSA-2008:0514

The remote host is missing updates announced in
advisory RHSA-2008:0514.

Evolution is the integrated collection of e-mail, calendaring, contact
management, communications and personal information management (PIM) tools
for the GNOME desktop environment.

A flaw was found in the way Evolution parsed iCalendar timezone attachment
data. If the Itip Formatter plug-in was disabled and a user opened a mail
with a carefully crafted iCalendar attachment, arbitrary code could be
executed as the user running Evolution. (CVE-2008-1108)

Note: the Itip Formatter plug-in, which allows calendar information
(attachments with a MIME type of text/calendar) to be displayed as part
of the e-mail message, is enabled by default.

A heap-based buffer overflow flaw was found in the way Evolution parsed
iCalendar attachments with an overly long DESCRIPTION property string. If
a user responded to a carefully crafted iCalendar attachment in a
particular way, arbitrary code could be executed as the user running
Evolution. (CVE-2008-1109).

The particular response required to trigger this vulnerability was as

1. Receive the carefully crafted iCalendar attachment.
2. Accept the associated meeting.
3. Open the calender the meeting was in.
4. Reply to the sender.

Red Hat would like to thank Alin Rad Pop of Secunia Research for
responsibly disclosing these issues.

All Evolution users should upgrade to these updated packages, which contain
backported patches which resolves these issues.
