Details

Updated evolution packages that fix two buffer overflow vulnerabilities are
now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

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
follows:

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.
