## Description

Cross-site request forgery (CSRF) vulnerability in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, allows remote attackers to hijack the authentication of arbitrary users for requests that were initiated by a plugin and received a 307 redirect to a page on a different web site.

## What to do
