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 &quot text/calendar&quot ) 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 &quot DESCRIPTION&quot 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.
