HP releases firmware “mitigation” for LaserJet vulnerability

We reported a while back that a security vulnerability had been discovered in some Hewlett-Packard LaserJet printers that could render them vulnerable to unauthorized access, although HP said there had been no real-world cases of such access occurring.
