[News] [Rival] Microsoft Tries to Sweep Serious DNS Flaws Under the Rug

SUBJECT: Microsoft SWI blog inaccuracies

,----[ Quote ]
| As you know, 3 weeks ago I published my paper, "Microsoft
| Windows DNS Stub Resolver Cache Poisoning"
| (http://www.trusteer.com/docs/Microsoft_Windows_resolver_DNS_cache_poiso
| ning.pdf),
| 
| simultaneously with Microsoft's release of MS08-020
| (http://www.microsoft.com/technet/security/Bulletin/MS08-020.mspx).
| A day later, Microsoft's Secure Windows
| Initiative (SWI) team published their blog entry for MS08-
| 020
| (http://blogs.technet.com/swi/archive/2008/04/09/ms08-020-how-predictabl
| e-is-the-dns-transaction-id.aspx).
| 
| Unfortunately, the SWI blog entry contains two serious
| mistakes. The first mistake is an inaccurate description of
| the PRNG used for the Microsoft Windows DNS client
| transaction ID. The second mistake is SWI's claim that
| "attackers cannot predict a guaranteed, known-next TXID
| exactly even with this weakness".
| 
| I contacted Microsoft about those mistakes, and while
| Microsoft did not refute my statements, they also refused
| to revise the blog entry. On one hand, I am inclined to tag
| this as a simple unwillingness on the side of the vendor to
| revise its materials and admit its mistakes. On the other
| hand, I cannot ignore the fact that the two mistakes, when
| combined, result in misleading the blog reader about the
| nature and the severity of the problem.
| 
| [...]
| 
| This is in stark contrast to SWI's claims. Furthermore,
| Microsoft did have the full paper (actually, a draft of it
| which contains all the relevant technical information) well
| before the SWI blog was published. So the problem here is
| not an issue of SWI not having access to the paper when
| they wrote their blog entry.

Once again caught lying. Like they did in Norway, Kenya and many other recent
scenarios. Pathological deniers.

| to 65 per cent over the last year. Use of BIND 8, by contrast, dropped from 
| 14 per cent in 2006 to 5.6 per cent this year. Usage of the Microsoft DNS 
| Server on web-facing systems also fell, decreasing to to 2.7 per cent in 2007
