A difficult to exploit vulnerability was discovered in versions of man prior to 1.5l. A bug exists in man that could cause a program named "unsafe" to be executed due to a malformed man file. In order to exploit this bug, a local attacker would have to be able to get another user to read the malformed man file, and the attacker would also have to create a file called "unsafe" that would be located somewhere in the victim's path.
