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"
