Description:
Przemysaw Frasunek has reported a vulnerability in mtr, which potentially can be exploited by malicious, local users to perform certain actions with escalated privileges.

The vulnerability is caused due to an off-by-one error in the keybinding routine in "mtr_curses_keyaction()". This may be exploited by supplying specially crafted, overly long input.

Successful exploitation may allow execution of arbitrary code with the privileges limited to hijacking raw sockets.

NOTE: Exploitation requires that mtr is setuid "root" and not compiled with gcc 3.x.

The vulnerability has been reported in versions 0.55 through 0.65.

Solution:
Update to version 0.67.
