GLSA-201707-08 : feh: Arbitrary remote code execution

critical Nessus Plugin ID 101339

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201707-08 (feh: Arbitrary remote code execution)

 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.

Solution

All feh users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/feh-2.18.3'
