CVE-2003-0972
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
