Microsoft, zlib, and Security Flaws

nakhla writes: "News.com is reporting that Microsoft's use of code from the open-source zlib library has led to possible security problems. The flaws in zlib were reported recently, and apply to several key Microsoft technologies, such as DirectX, Front Page, Install Shield, Office, and Internet Explorer. The article also mentions how this is not Microsoft's first use of open-source code in its software, but does point out that since zlib is not GPL'd they are under no obligation to release the source code to any of their products."
