This signature detects an attempt to exploit a buffer overflow vulnerability in WM Downloader application.
WM Downloader is a file download management application.
The application is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate checks on user-supplied input. Specifically, this issue occurs when parsing a specially crafted '.m3u' file.
Successfully exploiting this issue may allow remote attackers to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.
