CVE-2017-7875 low priority: Debian including 1 source packages (feh), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
