Description

IBM AIX is prone to a flaw in the way it loads libraries. The /usr/games/fortune binary uses a fixed path to look for specific files or libraries. This path includes directories that may not be trusted or under user control. By placing a custom version of the file or library in the path, the program will load it before the legitimate version. This allows a local attacker to inject custom code that will be run with the privilege of the program or user executing the program.
