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.

For Debian 7 'Wheezy', these problems have been fixed in version 2.3-2+deb7u1.

We recommend that you upgrade your feh packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
