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.
