## Description

Mozilla Firefox 3.5.2 on Windows XP, in some situations possibly involving an incompletely configured protocol handler, does not properly implement setting the document.location property to a value specifying a protocol associated with an external application, which allows remote attackers to cause a denial of service (memory consumption) via vectors involving a series of function calls that set this property, as demonstrated by (1) the chromehtml: protocol and (2) the aim: protocol.

## What to do
