xtokkaetama is prone to a locally exploitable buffer overflow vulnerability. This is due to insufficient bounds checking of the '-nickname' command line option, which could result in execution of arbitrary code in the context of the software.
|
|
|
|
The software is typically installed setgid 'games'.
