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

out-of-boundary heap write with the image viewer feh while receiving an
IPC message.

Workaround

There is no known workaround at this time.

Resolution

All feh users should upgrade to the latest version:
