Red Hat Security Advisory Synopsis: Important: evolution28 security update Advisory ID: RHSA-2008:0515-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0515.html Issue date: 2008-06-04 CVE Names: CVE-2008-1108 CVE-2008-1109 =====================================================================
  1. Summary:

Updated evolution28 packages that address two buffer overflow vulnerabilities are now available for Red Hat Enterprise Linux 4.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
