Problem description

This security update for Mozilla Firefox fixes following problems:
  • CAN-2005-0231: "Firetabbing" The javascript security manager usually prevents that a javascript: URL from one host is opened in a window displaying content from another host. But when the link is dropped to a tab, the security manager does not kick in. This can lead to several security problems scaling from stealing session cookies to the ability to run arbitrary code on the client system (depending on the displayed site or security setttings).
  • CAN-2005-0232: "Fireflashing" Using plugins like Flash and the -moz-opacity filter it is possible to display the about:config site in a hidden frame or a new window. By making the user double-click at a specific screen position (e.g. using a DHTML game) you can silently toggle the status of boolean config parameters.
  • CAN-2005-0233: "homograph attacks" / "IDN cloaking" Attackers may spoof hostnames by using translated hostname representation which look exactly the same as the original host, allowing phishing attacks or similar. We now show both IDN punycode and visible form of the hostname.
  • CAN-2005-0255: Attackers could cause overflows or crashes in low memory situations.
  • Additional Firefox bugfixes from the 1.0.1 release.
