Looks like most of us will be safe...
From Wired.com:
"Sony BMG, yielding to consumer concern, said on Wednesday it was recalling music CDs containing copy-protection software that acts like virus software and hides deep inside a computer.
Sony BMG has used the XCP copy-protection software on 49 titles from artists such as Celine Dion and Sarah McLachlan and produced an estimated 4.7 million music CDs. Around 2.1 million units have been sold on to consumers.
The software, developed by a British firm, First4Internet, installs itself on a personal computer used to play the CD in order to guard against copying, but it leaves the back door open for malicious hackers."
