PC World posted a story that about 40 different Windows applications contain a critical flaw according to a security researcher

The bug was patched by Apple in its iTunes software for Windows four months ago, but remains in more than three dozen other Windows programs, said HD Moore, the chief security officer of Rapid7 and creator of the open-source Metasploit penetration testing toolkit. Moore did not reveal the names of the vulnerable applications or their makers, however.

Each affected program will have to be patched separately.
