Integer signedness error in ansi.c for GNU screen 4.0.1 and earlier, and 3.9.15 and earlier, allows local users to execute arbitrary code via a large number of ";" (semicolon) characters in escape sequences, which leads to a buffer overflow.

Security readout for executives and security teams

CVE-2003-0972 is a local vulnerability in older GNU screen versions. A user who already has local access could trigger a buffer overflow and execute arbitrary code. This is most urgent for shared UNIX/Linux systems, legacy servers, or environments where untrusted users can obtain shell access. Exposure is likely limited to systems running legacy GNU screen packages in the affected version ranges. Risk is higher on multi-user systems, bastion hosts, lab servers, and any environment where non-administrative users have shell access. Treat this as a high-priority legacy hygiene issue where GNU screen exists on shared or sensitive systems. It is local-only based on supplied evidence, but arbitrary code execution can support privilege escalation chains or compromise shared infrastructure. Mitigation focus: Identify GNU screen versions across managed systems.; Upgrade GNU screen according to relevant vendor advisories.; Prioritize shared systems with local shell users..
