A vulnerability in feh might allow remote attackers to execute arbitrary code.
| Package | media-gfx/feh on all architectures |
|---|---|
| Affected versions | < 2.18.3 |
| Unaffected versions | >= 2.18.3 |
feh is an X11 image viewer aimed mostly at console users.
Tobias Stoeckmann discovered it was possible to trigger an out-of-boundary heap write with the image viewer feh while receiving an IPC message.
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.
There is no known workaround at this time.
All feh users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/feh-2.18.3"
