Mozilla Foundation Security Advisory 2006-71
Title: LiveConnect crash finalizing JS objects
Impact: Critical
Announced: December 19, 2006
Reporter: Steven Michaud
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 2.0.0.1
Firefox 1.5.0.9
Thunderbird 1.5.0.9
SeaMonkey 1.0.7
Description
Steven Michaud reported a crash in LiveConnect, the bridge code that allows
Java applets and web JavaScript to communicate. The crash is due to re-use of
an already-freed object and we presume this could be exploited with enough
effort.
Note: Thunderbird does not load Java applets or other plugins in mail messages
and is therefore not vulnerable to this flaw unless a user has customized their
version of Thunderbird to remove this restriction.
Workaround
Disable Java to disable LiveConnect until you install a fixed version.
