Gentoo Linux Security Advisory

Title: feh: Arbitrary remote code execution (GLSA 201707-08)
Severity: normal
Exploitable: remote
Date: 2017-07-08
Updated: 2017-08-06
Bug(s): #616470
ID: 201707-08

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: media-gfx/feh
Vulnerable: < 2.18.3
Unaffected: >= 2.18.3
Architectures: All supported architectures


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