The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
High
AC
The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques. The attacker must have additional methods available to bypass security measures in place. For example, circumvention of address space randomization (ASLR) or data execution prevention must be performed for the attack to be successful. Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Unfortunately, the wise guys at Adobe don't know the platform on which their
product runs and include the MSVC++ 2008 and 2010 runtimes via MSI merge module.
Due to a well-known idiosyncrasy of Windows Update Agent M$FT components
installed via MSI merge module are NOT detected and thus not updated by M$FT ...
although M$FT advises their users to do so!
>From the FAQ section of
<http://www.microsoft.com/technet/security/bulletin/ms11-025>
| In the case where a system has no MFC applications currently installed but
| does have the vulnerable Visual Studio or Visual C++ runtimes installed,
| Microsoft recommends that users install this update as a defense-in-depth
| measure, in case of an attack vector being introduced or becoming known at
| a later time.
4. Additionally, the following dangling references to Acrobat.exe are created:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.acrobatsecuritysettings\OpenWithList\Acrobat.exe]
@=""
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdfxml\OpenWithList\Acrobat.exe]
@=""
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AcroExch.Document.11\protocol\StdFileEditing\server]
@="\"Acrobat.exe\""
The latter allows the execution of a rogue program named "Acrobat.exe" from
CWD via OLE in the security context of the logged on user.
Cf. <http://technet.microsoft.com/security/advisory/2269637>
5. On Window XP the following superfluous registry entries are created:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Low Rights]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Low Rights\ElevationPolicy]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Low Rights\ElevationPolicy\{15B3FB63-66F4-4EFC-B717-BB283B85E79B}]
"Policy"=dword:00000003

"AppName"="AcroBroker.exe"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Low Rights\ElevationPolicy\{358E6F10-DE8A-4602-8424-179CA217F8EE}]

If the wise guys at Adobe know the platform on which their product runs
a little better they'd probably know that "Low Rights\Elevation Policy"
is supported on Windows Vista and later only.

Windows XP are superfluous too (at least when Outlook 2007 is not
installed).
