CVE-2003-0063 — Improper Neutralization of Escape, Meta, or Control Sequences in Project X11r6

The xterm terminal emulator in XFree86 4.2.0 and earlier allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.
