Descriptions

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.

Un atacante remoto autentificado puede obtener acceso a un puntero desreferenciado contenido en una solicitud. Los accesos pueden llevar posteriormente a la sobreescritura local de la memoria en el CmpTraceMgr, por lo que el atacante no puede obtener los valores leídos internamente ni controlar los valores a escribir. Si se accede a una memoria no válida, se produce un fallo
