Description Josh Bressers 2009-07-16 14:28:43 UTC

Mozilla developer Blake Kaplan reported that setTimeout, when called with
certain object parameters which should be protected with a
XPCNativeWrapper, will fail to keep the object wrapped when compiling the
new function to be executed. If chrome privileged code were to call
setTimeout using this as an argument, the this object will lose its wrapper
and could be unsafely accessed by chrome code. An attacker could use such
vulnerable code to run arbitrary JavaScript with chrome privileges.

Comment 3 Jan Lieskovsky 2009-07-22 18:56:21 UTC

MITRE's CVE-2009-2471 entry:

The setTimeout function in Mozilla Firefox before 3.0.12 does not
properly preserve object wrapping, which allows remote attackers to
execute arbitrary JavaScript with chrome privileges via a crafted
call, related to XPCNativeWrapper.
