Mozilla products fail to properly validate references returned by JavaScript constructors. This vulnerability may allow a remote attacker to execute arbitrary code on a vulnerable system.
According to Mozilla Foundation Security Advisory 2006-51:
JavaScript functions have a parent object created using the standard Object() constructor (ECMA-specified behavior) and that this constructor can be redefined by script (also ECMA-specified behavior). If the Object() constructor is changed to return a reference to a privileged object with useful properties it is possible to have attacker-supplied script executed with elevated privileges by calling the function. This could be used to install malware or take other malicious actions.
For more information and a complete list of affected products, refer to Mozilla Foundation Security Advisory 2006-51.
A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. The attacker could also cause the vulnerable application to crash.
