Symantec Security Advisory SYMSA-2007-005[1]is now available. This covers a Teredo-related vulnerability in theVista version of Windows Firewall (BID 24779, CVE-2007-3038). (To beclear, this vulnerability is not connected to any of the nine Vistaissues I discussed in my last blog[2].)
Last fall, when Ollie Whitehouse[3] was analyzing whatTCP ports were open over a Teredo interface in a freshly installedWindows Vista RC2, he discovered that port 5357 was open over Teredo.We thought this odd since there is no functional reason this port,which corresponds to Web Services on Devices (WSD)[4], should beremotely accessible. When the release version of Vista becameavailable, we verified that this port was still open. (...
We don't feel that most of the issues are especially significant.Microsoft reviewed the paper prior to its public release and Symantecwould participate in any warranted responsible disclosure forvulnerabilities.
Greetings. For the last four months we have been busy taking a lookat the release (RTM) version of Windows Vista in an effort to updateour Windows Vista Network Attack Surface Analysis report fromlast July, which covered beta builds of Vista. To broaden and deepenour research, we have retested the results in the first report andexpanded our investigation of certain topics.
As of today, the new reportis available to you. The paper is 118 pages long, but don't worry, youdon't have to read it all! You can skip to the parts you are mostinterested in, or take a look at the 13 pages that summarize theresults in the paper. In addition, the appendices provide details ofour methodology and results. We hope you find this report useful as aWindows Vista network reference, and we hope you find value in both thedetailed security analysis and in the broad overview.
