In addition to these main issues, the update contains a number of security fixes for Windows and Mac OS systems, including corrections to the handling of JPEG and TIFF files, and the "libpng" library that could result in arbitrary code execution. In addition, some the update fixes problems where improper XML handling could result in a program crash and arbitrary code execution. Lastly, numerous memory mismanagement issues with Webkit could also result in program crashes.
Besides crashes, there is a fix for the improper handling of user credentials when using basic HTTP authentication, and fixes to WebKit and other underlying technologies to address the following cross-contamination problems.
  • Injection of CSS styles from a malicious site into other open Web pages
  • Improper handling of caches from malicious sites that could cause malfunction of other Web sites
  • Disclosure of information entered in one site to another with HTML5 drag-and-drop
  • Cross-origin issues with malicious sites causing files to be sent to an unknown remote server
  • The possibility of a malicious site when using the "Web Inspector" could result in script execution that could affect other open sites.
