Rogue 5.3 - Local Buffer Overflow

source: https://www.securityfocus.com/bid/5837/info

Rogue is a game included with BSD distributions including FreeBSD and NetBSD.

By passing an overly long value when restoring a saved game, it is possible for an attacker to corrupt memory. Exploitation of this issue could result in privilege escalation to the 'games' group, further resulting in the corruption of saved game data, as well as storage consumption.
