1. Microsoft Security News
1.1 Bill Gates Announces New Focus on Security
In an email message sent to all Microsoft employees, Bill Gates
outlines Microsoft's new strategy for "Trustworthy Computing",
emphasizing availability, security, and privacy. Gates states
that "great features won't matter unless customers trust
our software...now, when we face a choice between adding
features and resolving security issues, we need to choose
security". The full text of Gates' message is reprinted at
http://www.wired.com/news/business/0,1367,49826,00.html.

1.2 Microsoft Releases New Version 3.3 of hfnetchk.exe
On January 17, Microsoft released version 3.3 of its network hot
fix checker (hfnetchk.exe). The updated version fixes various bugs,
provides new command-line options, and installs support for the future
releases of .NET Server and IIS 6.0. Future versions of the tool
will add support for Exchange, Office, and other Microsoft products.
(Note: version 3.31 was released on January 21 to fix an issue with
hfnetchk and SQL Server 7.0.)

1.3 Microsoft Releases Security Rollup Package (SRP1) for Windows 2000
In late January, Microsoft released Security Rollup Package 1 (SRP1)
for Windows 2000, the first cumulative patch released for the OS
since Service Pack 2 (SP2). The rollup uses a single patch to fix
various security vulnerabilities from 2000 and 2001, roughly up to and
including MS01-052. Security Rollup Packages are part of Microsoft's
Strategic Technology Protection Program, intended to provide periodic
rollups to simplify the installation of multiple patches. They are
not a replacement for Service Packs (SP3 for Win2K is still expected
during the first half of 2002).

Section II: Security Alert Summary
3. Microsoft Security Bulletins
3.1 MS02-001: Trusting Domains Do Not Verify Domain Membership of
SIDs in Authorization Data (30 January 2002)
Risk: **MODERATE
- Internet systems: LOW
- Intranet systems: MODERATE
- Client systems: n/a
Impact: privilege elevation
Systems Affected:
- Windows 2000
- Windows NT 4.0
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable
Summary:
A vulnerability exists in the authentication mechanism used by
Windows 2000 and Windows NT domain controllers when a trusting domain
authenticates a user from a trusted domain. The trusting domain
does not verify that the trusted domain is actually authoritative
for the user and group SIDs that are passed with the authentication
information. An attacker could include a SID that was not part of
the trusted domain, the trusting domain would still accept that SID,
allowing the attacker to elevate his privileges to those of any user
or group. The attacker would need to have Administrator privileges
in the trusted domain to carry out this attack. SID Filtering (see
below) can be used to screen out such attacks, but may have an impact
on normal operations.

4.1 Internet Explorer Issues
4.1.1 Internet Explorer GetObject File Disclosure
* Risk: Moderate
* Impact: information disclosure
* Summary: A flaw in the Jscript GetObject() function, when combined
with the ActiveX object 'htmlfile', could be used to allow an attacker
to read any file on the user's hard drive, if the file location was
known. The flaw could be exploited via a specially crafted script
placed on a web site. A workaround is to disable Active Scripting.

4.1.4 Internet Explorer JavaScript File Enumeration Vulnerability
* Risk: Low
* Impact: information disclosure
* Summary: The onError event handler can be used in conjunction with a
file request to determine whether or not the requested file exists,
including files on the local hard disk outside of the web root.
If the requested file does NOT exist, the onError event handler will
run if it is enabled. This could be used for reconnaissance purposes
to plan further attacks.

* Risk: Low
* Impact: unauthorized modification of log files
* Summary: Internet Information Server 4.0 (IIS 4.0) allows shared
(concurrent) access to the IIS log files. Default NTFS permissions on
the log files allow unprivileged users (specifically the IUSR account
and members of the Everyone group) to modify the files, which would
allow an attacker to modify log entries to cover his tracks.

5. Virus Alerts
5.1 W32/MyParty worm
The W32/MyParty worm spread rapidly during late January. The worm is
a mass-mailing worm that propagates by sending itself to contacts in
the Windows address book and to addresses found in Outlook Express.
W32/MyParty also installs a backdoor Trojan that allows the author
to access the user's computer. The worm only propagates between
January 25 and January 29, but will remain active on the system at
other times. A variant (W32/MyParty.B) contains an identical payload
but will propagate between January 20 and January 24.
More information:

mm.html
++++++++++
5.2 W32/Donut virus
The W32/Donut virus was discovered in early January. The virus has no
destructive payload; it is a "concept virus" designed simply to display
a message stating "This cell has been infected by dotNET virus!".
Due to a bug in the code, the message does not display properly.
However, the virus is of interest because it specifically targets
Microsoft's .NET architecture.

5.3 SWF.LFM.926, ACTS.LFM.926
Another "proof of concept" virus, SWF.LFM.926 is the first known
virus to be carried by Macromedia Shockwave Flash files (*.swf).
The virus displays a Flash animation and will infect other *.swf
files found on the system. Many anti-virus products do not scan
*.swf files by default.

7. Updates
7.1 Increased Scanning to Port 1433 - Users Urged to Install SQL
Server Patches. The Computer Incident Advisory Capability (CIAC -
http://www.ciac.org/ciac/) of the Department of Energy reports a
significant increase in scans for TCP port 1433, which is used by
Microsoft's SQL Server. Microsoft released security bulletin MS01-060
(reported in last month's Windows Digest), which outlined several
buffer overflows in SQL Server. The increase in scanning activity
implies that an exploit may exist in active circulation. Users are
urged to apply the appropriate patches. See MS01-060 for details,
http://www.microsoft.com/technet/security/bulletin/MS01-060.asp
7.2 AOL Fixes AIM Buffer Overflow
AOL has fixed a major buffer overflow problem in AOL Instant
Messenger (AIM) by patching the flaw on its AIM servers.
The vulnerability was originally discovered by w00w00
(http://www.w00w00.org/advisories/aim.html and was reported in last
month's Windows Digest.
7.3 w00w00-recommended Fix for AIM Buffer Overflow Contains Backdoors,
Spyware
In the original w00w00 advisory for the AIM Buffer Overflow
described above, w00w00 recommended the use of the AIM
Filter software as a temporary fix until a patch was issued
by AOL. AIM Filter was later discovered to contain backdoors
and spyware. Uninstalling AIM Filter resolves this problem.
