Below are the dates of release and the vulnerability which has been
exploited

October 13, 2005; MS05-047 (umpnpmgr.dll) Trigger for the bug in
umpnpmgr.dll

As of now, these PoCs are only available to Immunitysec Customers,
but once this goes public, I fear we maybe in for another
WORM_ZOTOB like episode.

eEye Digital Security has currently released
four published advisories that provides technical details about the
four out of nine vulnerabilities that have been found recently on
Microsoft products.


These advisories are publicly available and provides some proof of
concept exploit codes. The links below points to the published
advisories of each vulnerability.

MS05-047

Vulnerability in Plug and Play Could Allow Remote Code Execution
and Local Elevation of Privilege (905749)
PoC

MS05-050

Vulnerability in DirectShow Could Allow Remote Code Execution
(904706)
PoC

MS05-051

Vulnerabilities in MSDTC and COM+ Could Allow Remote Code Execution
(902400)
PoC

MS05-052

Cumulative Security Update for Internet Explorer (896688)
PoC


Noted on these advisories, the team is proactively monitoring for
malwares that may implement these exploits as an added “jitsu” for
propagation or any malicious activity.

FrSIRT has just posted three full blown
exploits for the new MS vulnerabilities. See the details by
following the links below.


Microsoft Windows FTP Client File Transfer Location Tampering
Exploit (MS05-044)

Date : 13/10/2005


Microsoft Windows Network Connection Manager Local DoS Exploit
(MS05-045)

Date : 13/10/2005


Microsoft Collaboration Data Objects Buffer Overflow PoC Exploit
(MS05-048)

Date : 13/10/2005


Whew! It seems like there is no stopping now, eight (8) out of nine
(9) new Microsoft vulnerabilities already have exploit codes! If
you remember, two (2) days has just passed since the released of 9
MS vulnerabilities and now this is what we got as summarized
below.

• Total of 8 exploit codes out of 9 MS vulnerabilities
  
• Two exploit codes for MS05-047
  
• Two exploit codes for MS05-051
  

As of now, only MS05-049 lacks exploit code.


Well, as we have just noticed the developments of various exploits
for each MS vulnerability is really fast. We won’t be surprised if
just later this day or the next day a new or repacked malware will
be implementing this exploit!
