List of important fixes included:

  • Out-of-bounds read and write vulnerability in the JavaScript subset “asm.js” during the validation procedure, whose exploitation could lead attacker to read parts of the memory that may contain users sensitive data.
  • Buffer overflow in the way the browser parses compressed XML.
  • Includes feature that enables the use of DRM-enabled (Digital Rights Management-enabled) video content in Firefox.
  • Includes integration with Adobe Content Decryption Module (CDM), allowing users to play DRM-wrapped content in HTML5 video tag.
  • Designed sandbox that encompasses CDM, restricting interaction with sensitive parts of the system and the browser.
