Descriptions
An out-of-bounds write in "ClearKeyDecryptor" while decrypting some Clearkey-encrypted media content. The "ClearKeyDecryptor" code runs within the Gecko Media Plugin (GMP) sandbox. If a second mechanism is found to escape the sandbox, this vulnerability allows for the writing of arbitrary data within memory, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
Escritura fuera de límites en "ClearKeyDecryptor" mientras se descodifican algunos contenidos multimedia cifrados mediante Clearkey. El código "ClearKeyDecryptor" se ejecuta en el sandbox Gecko Media Plugin (GMP). Si se descubre que un segundo mecanismo escapa del sandbox, esta vulnerabilidad permite la escritura de datos arbitrarios en la memoria, lo que resulta en un cierre inesperado potencialmente explotable. La vulnerabilidad afecta a Firefox ESR en versiones anteriores a la 45.9, Firefox ESR en versiones anteriores a la 52.1 y Firefox en versiones anteriores a la 53.
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 results from the lack of proper validation of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute arbitrary code under the context of the plugin-container container process.
