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	Architecture(s)
gnome-extra/evolution-data-server	< 1.8.3-r5	>= 1.8.3-r5	All supported architectures

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

All Evolution users should upgrade evolution-data-server to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose "gnome-extra/evolution-data-server"
