FreeBSD : mozilla -- 'Wrapped' javascript: urls bypass security checks (a81746a1-c2c7-11d9-89f7-02061b08fc24)

high Nessus Plugin ID 19070

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

A Mozilla Foundation Security Advisory reports :

Some security checks intended to prevent script injection were incorrect and could be bypassed by wrapping a javascript: url in the view-source : pseudo-protocol. Michael Krax demonstrated that a variant of his favicon exploit could still execute arbitrary code, and the same technique could also be used to perform cross-site scripting.

Georgi Guninski demonstrated the same flaw wrapping javascript: urls with the jar: pseudo-protocol.

L. David Baron discovered a nested variant that defeated checks in the script security manager.

Workaround: Disable JavaScript

Solution

Update the affected packages.
