This signature detects an attempt to exploit a buffer overflow vulnerability in CCMPlayer application which may result in remote code execution.
CCMPlayer is a multimedia player application.
The application is prone to a remote stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. Specifically, the application fails to handle specially crafted '.m3u' playlist files.
Attackers can exploit this issue to execute arbitrary code within the context of the application. Failed attacks may cause a denial-of-service condition.
