iTunes 12.1 for Windows: still outdated and VULNERABLE 3rd party libraries, still UNQUOTED and VULNERABLE pathnames C:\Program Files\...

["Stefan Kanthak" <stefan.kanthak () nexgo de>]

Hi @ll,

See <http://seclists.org/bugtraq/2014/Oct/164>,
<http://seclists.org/fulldisclosure/2014/Oct/109>,
<http://seclists.org/fulldisclosure/2014/Aug/44>,
<http://seclists.org/fulldisclosure/2014/Aug/33> and
<http://seclists.org/fulldisclosure/2014/Jul/30> for the
prequel.


The just released iTunes 12.1 for Windows comes again with
outdated and VULNERABLE 3rd party libraries.

In AppleMobileDeviceSupport.msi:

* libeay32.dll and ssleay32.dll 0.9.8za from 2014-06-05

  The current version is 0.9.8ze and has 21 security fixes
  which are missing in 0.9.8za; see <http://openssl.org/news/>

  At last, these DLLs are no more 7 years old as before, but
  "only" 7 months old.


* libcurl.dll 7.16.2

  is almost EIGHT years old and has at least 22 unfixed CVEs!

  The current version is 7.40.0; for the fixed vulnerabilities
  see <http://curl.haxx.se/docs/security.html>


In AppleApplicationSupport.msi:

* msvcr100.dll and msvcp100.dll 10.0.40219.1 from 2011-02-20

  These are the runtime DLLs for Visual C++ 2010 RTM.

  The current version is but 10.0.40219.325; see
  https://technet.microsoft.com/library/security/bulletin/MS11-025



Additionally the following VULNERABLE[*] command lines with unquoted
pathnames containing spaces are registered.

By AppleApplicationSupport.msi:

[HKEY_CLASSES_ROOT\CLSID\{fdd068c2-d51a-4175-8a20-5cbc704ea3bd}\LocalServer32]
@="[#AppleApplicationSupport_APSDaemon.exe]"

[HKEY_CLASSES_ROOT\CLSID\{6812639B-FD61-4329-9901-22CFDBD690FE}\LocalServer32]
@="[#AppleApplicationSupport_APSDaemon.exe]"

[HKEY_CLASSES_ROOT\CLSID\{D9E904CA-8865-42E7-B0F0-B7B8C4D54D70}\LocalServer32]
@="[#AppleApplicationSupport_APSDaemon.exe]"


For beginners: the value of the unnamed registry entry is a COMMAND
LINE and has to be quoted properly!

> From <https://msdn.microsoft.com/library/ms683844.aspx>

| To help provide system security, use quoted strings in the path to
| indicate where the executable filename ends and the arguments begin. 

As of Windows 2003 developers who are NOT completely unaware of
Microsofts documentation might want to use the "ServerExecutable"
registry entry described there too.
But 12 years are surely way too short for Apple's developers, QA and
management to learn about such "new" features which help improve safety
and security.


By iTunes.msi:

[HKEY_CLASSES_ROOT\itms\shell\open\command]
@="[#iTunes.exe] /url \"%1\""

[HKEY_CLASSES_ROOT\iTunes\shell\open\command]
@="[#iTunes.exe] /url \"%1\""

[HKEY_CLASSES_ROOT\itsradio\shell\open\command]
@="[#iTunes.exe] /url \"%1\""

[HKEY_CLASSES_ROOT\itunesradio\shell\open\command]
@="[#iTunes.exe] /url \"%1\""

[HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Media\iTunes\shell\open\command]

[HKEY_CLASSES_ROOT\iTunes.AssocProtocol.pcast\shell\open\command]
@="[INSTALLDIR]iTunes.exe /url \"%1\""


> From <http://msdn.microsoft.com/library/cc144175.aspx>:

| If any element of the command string contains or might contain
| spaces, it must be enclosed in quotation marks. Otherwise, if
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| the element contains a space, it will not parse correctly.


See <http://home.arcor.de/skanthak/sentinel.html> if you want to
detect software with this 20+ year old vulnerability[*] without
dissecting its *.MSI files.


Until Apple's developers, their QA and their managers start to
develop a sense for their customers safety and security:
stay away from Apple's (Windows) software!


stay tuned
