Secunia reported today about a new exploit for Firefox 184.108.40.206 (might affect previous builds as well).
A vulnerability has been discovered in Firefox, which can be exploited by malicious people to compromise a user’s system.
Do not browse untrusted sites.
Disable the “Firefox URL” URI handler.
Thor Larholm noted:
There is an input validation flaw in Internet Explorer that allows you to specify arbitrary arguments to the process responsible for handling URL protocols. This is the same type of input validation vulnerability that I discovered in the Safari 3 beta.
