The Register is reporting that software Sony has released to fix the security hole in its Sunncomm DRM protected CDs actually has the same bug and can cause more problems for users.
It seems to me this was a knee jerk reaction to get patches out, unfortunately the people Sony are using have poor design and/or programming skills and/or no quality assurance.
On top of this Sony seems to be showing a complete lack of adequate leadership skills, they, or a third party on Sony's behalf should have properly checked the work. The cost and delay of adequate testing could have prevented the whole situation and saved money and face. Sony's behaviour and reaction to this whole debacle reeks of amateurism and incompetance for a company that once was synonymous with quality products.
