Description Andrej Nemec 2017-04-20 13:57:35 UTC 
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.
