Synopsis
========

A vulnerability in feh might allow remote attackers to execute
arbitrary code.

Background
==========

feh is an X11 image viewer aimed mostly at console users.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/feh < 2.18.3 >= 2.18.3

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

Tobias Stoeckmann discovered it was possible to trigger an
out-of-boundary heap write with the image viewer feh while receiving an
IPC message.

Impact
======

A remote attacker, pretending to be the E17 window manager, could
possibly trigger an out-of-boundary heap write in feh while receiving
an IPC message. This could result in execution of arbitrary code with
the privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All feh users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/feh-2.18.3"

References
