Severity:	normal
Title:	Evolution: User-assisted execution of arbitrary code
Date:	06/16/2008
Bugs:	#223963
ID:	200806-06

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	Architecture(s)
mail-client/evolution	< 2.12.3-r2	>= 2.12.3-r2	All supported architectures

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"
