Description
socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a denial of service or disruption of the target process.
A flaw was found in screen. This flaw allows local users to send a SIGHUP signal to any PID due to a missing signal sending permission check, potentially resulting in a denial of service or disruption of the target process.
