Note: Versions mentioned in the description apply only to the upstream feh package and not the feh package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
In wallpaper.c in feh before v2.18.3, if a malicious client pretends to be the E17 window manager, it is possible to trigger an out-of-boundary heap write while receiving an IPC message. An integer overflow leads to a buffer overflow and/or a double free.
