Descriptions
Heap-based buffer overflow in the ClearKey Content Decryption Module (CDM) in the Encrypted Media Extensions (EME) API in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 might allow remote attackers to execute arbitrary code by providing a malformed video and leveraging a Gecko Media Plugin (GMP) sandbox bypass.
Desbordamiento de búfer basado en memoria dinámica en el ClearKey Content Decryption Module (CDM) en el Encrypted Media Extensions (EME) API en Mozilla Firefox en versiones anteriores a 48.0 y Firefox ESR 45.x en versiones anteriores a 45.3 podría permitir a atacantes remotos ejecutar código arbitrario proporcionando un vídeo malformado y aprovechando un Gecko Media Plugin (GMP) sandbox bypass.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of ClearKey encrypted media. The issue lies in the failure to validate the length of encrypted data prior to copying into a heap-based buffer. An attacker can leverage this vulnerability to execute code within the context of the current process.
