Re: [Full-Disclosure] RE: Microsoft Baseline Security Analyzer not seeing KB887742 and KB886185



Actually, the KB article is incorrect. Only other users from the same dial-up ISP given IP's considered in the same "local" subnet would be able to have NBT traffic considered local and thus pass through the firewall. It is not "anyone on the Internet" as the KB states. They would still need a username and password to access the resource. Additionally, one should note that on non-domain member systems, administrators would have to explicitly allow FPS exceptions after the fact for this to be an issue in the first place, and even so, only after going in and manually binding FPS to the dial-up interface which is disabled by default. You really have to go around your gluteus maximus to present this as an issue. So, IMO, it is not a major security hole.

The Invalid_Process_Attach_Attempt bug does not have security implications, though in particular configurations a DOS does condition exists. DOS != security vulnerability in this case.

But, not withstanding the above caveats, I agree with you that 886185 is still a potential security issue, and for that reason, should be checked by MBSA.

KB887742: "A computer that is running Microsoft Windows XP Service Pack
2 (SP2), Microsoft Windows XP Tablet PC Edition 2005, or Microsoft
Windows Server 2003 unexpectedly stops. Additionally, the following Stop
error message appears on a blue screen: Stop 0x05
(INVALID_PROCESS_ATTACH_ATTEMPT)".

That's a denial of service.  There are security implications there.

KB886185: "After you set up Windows Firewall in Microsoft Windows XP
Service Pack 2 (SP2), you may discover that anyone on the Internet can
access resources on your computer when you use a dial-up connection to
connect to the Internet."

That looks like a major security hole to me.

Cheers,

Phil

These are not security updates.  KB887742 is for a stop error
(http://support.microsoft.com/kb/887742) and  KB886185 is an
update for network scope on the Windows Firewall
(http://support.microsoft.com/default.aspx?scid=kb;en-us;886185) .

The MBSA scans for Security Updates only, not every hotfix
ever released.  Note that a "Critical" patch is not
necessarily a "Security"
patch.  You may be thinking of the "Maximum severity" levels
of the MS*-xxx security bulletins which are not the same thing.

Subject: Microsoft Baseline Security Analyzer not seeing KB887742 and
KB886185

Subject line says it all....just did a fresh install of WinXP
SP2....was using MBSAFU to make sure it would patch...which
it did.  However Windows Update shows still needing KB887742
and KB886185.  MBSA shows no critical patches need updated.
Systeminfo shows that both KB887742 and
KB886185 are NOT installed.  I'm using latest MBSA.  Anyone
else see this?  Kinda sucks :(
