GNU » Screen : Security Vulnerabilities, CVEs, (Overflow)

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.

A buffer overflow was found in the way GNU Screen before 4.8.0 treated the special escape OSC 49. Specially crafted output, or a special program, could corrupt memory and crash Screen or possibly have unspecified other impact.

Buffer overflow in the Braille module for GNU screen 3.9.11, when HAVE_BRAILLE is defined, allows local users to execute arbitrary code.
