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"
