Technical description

Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle certain redirections involving data: URLs and Java LiveConnect scripts, which allows remote attackers to start processes, read arbitrary local files, and establish network connections via vectors involving a refresh value in the http-equiv attribute of a META element, which causes the wrong security principal to be used.

Remediation

Check the references section for vendor advisories and patches from mozilla. Update firefox to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
