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.
