Evolution: User-assisted execution of arbitrary code

Background

Evolution is the mail client of the GNOME desktop environment.

Description

Alin Rad Pop (Secunia Research) reported two vulnerabilities in Evolution:

• A boundary error exists when parsing overly long timezone strings contained within iCalendar attachments and when the ITip formatter is disabled (CVE-2008-1108).
• A boundary error exists when replying to an iCalendar request with an overly long “DESCRIPTION” property while in calendar view (CVE-2008-1109).

Impact

A remote attacker could entice a user to open a specially crafted iCalendar attachment, resulting in the execution of arbitrary code with the privileges of the user running Evolution.

Workaround

There is no known workaround at this time.

Resolution

All Evolution users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=mail-client/evolution-2.12.3-r2"
