EFF and Sony-BMG today announced the existence of a new security vulnerability that affects Sony-BMG CDs that include SunnComm MediaMax Version 5 copy protection software. The vulnerability was discovered by the security firm iSEC Partners after EFF requested an examination of the SunnComm software.
For more on the vulnerability, including whether you might be affected, see EFF's FAQ on it. Sony-BMG and SunnComm have released a patch
that affected users should install immediately.
This security vulnerability is distinct from and affects different CDs from the one reported in early November in connection with the First4Internet XCP software. Sony-BMG has disclosed a full list of the 27 CDs that include the SunnComm MediaMax Version 5.
UPDATE: A further security vulnerability has been reported that afflicts MediaMax and Sony-BMG's patch. As a result, we are recommending against use of the patch until this new vulnerability is addressed.
