Background ========== xterm is a terminal emulator for the X Window system. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-terms/xterm < 239 >= 239 Description =========== Paul Szabo reported an insufficient input sanitization when processing Device Control Request Status String (DECRQSS) sequences.
