Sony's SunnComm DRM Patch a Security Risk

Spad writes "The BBC is reporting that mere days after the EFF and Sony announced a patch to fix the vulnerability in its SunnComm DRM system, security researchers Ed Felten and Alex Halderman have discovered that the patch itself introduces yet more vulnerabilities. They have now asked users not to apply the patch and are urging Sony to recall all of the affected CDs from sale. Sony has said that approximately six million CDs using [SunnComm] MediaMax have been shipped to stores. Affected artists include Alicia Keys, Britney Spears, Black Rebel Motorcycle Club and Faithless."
