Synopsis
========

The IMAP client of Evolution contains a vulnerability potentially
leading to the execution of arbitrary code.

Background
==========

Evolution is the mail client of the GNOME desktop environment. Camel is
the Evolution Data Server module that handles mail functions.

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

    -------------------------------------------------------------------
     Package                            /  Vulnerable  /    Unaffected
    -------------------------------------------------------------------
  1  gnome-extra/evolution-data-server     < 1.10.3.1      >= 1.10.3.1

Description
===========

The imap_rescan() function of the file camel-imap-folder.c does not
properly sanitize the "SEQUENCE" response sent by an IMAP server before
being used to index arrays.

Impact
======

A malicious or compromised IMAP server could trigger the vulnerability
and execute arbitrary code with the permissions of the user running
Evolution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

Note that this GLSA addresses the same issue as GLSA 200707-03, but for
the 1.10 branch of Evolution Data Server.

All Evolution users should upgrade to the latest version:

   # emerge --sync
   # emerge -av --oneshot ">=gnome-extra/evolution-data-server-1.10.3.1"
