Descriptions

A buffer overflow was discovered in the URL-authentication backend of the Icecast before 2.4.4. If the backend is enabled, then any malicious HTTP client can send a request for that specific resource including a crafted header, leading to denial of service and potentially remote code execution.

Se ha descubierto un desbordamiento de búfer en el backend de autenticación de URL en Icecast en versiones anteriores a la 2.4.4. Si el backend está habilitado, cualquier cliente HTTP malicioso puede enviar una petición para ese recurso concreto incluyendo una cabecera manipulada, lo que conduce a una denegación de servicio y a la potencial ejecución remota de código.
