The GNU Screen utility versions 4.0.1, 3.9.15, and below, suffer from a buffer overflow vulnerability that allows local users to escalate their privileges. The screen utility is installed either setgid-utmp or setuid-root. It also has some potential for remote attacks and allows an attacker to get control of another user's screen, providing a 2-3 gigabyte transfer of data needed to exploit this vulnerability.
