Description |
The xterm terminal emulator contains a flaw that may allow a local malicious user to overflow a buffer associated to the inputMethod, preeditType, and *Keymap resources. The issue is triggered when a specially crafted string containing machine code is used to set a specific resource. It is possible that the flaw may allow the user to gain root privileges by spawning a setuid-root shell resulting in a loss of system integrity.

Simply remove the setuid root bit from the xterm binary:
chmod 0755 /path/to/xterm
