Synopsis
========

Multiple vulnerabilities in Evolution may allow for user-assisted
execution of arbitrary code.

Background
==========

Evolution is the mail client of the GNOME desktop environment.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/evolution < 2.12.3-r2 >= 2.12.3-r2

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"
