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"
