Description:
Microsoft has issued patches for Microsoft Windows to fix a vulnerability in the Help and Support Center.
The vulnerability is caused due to a boundary error in the file associated with the HCP protocol. This can be exploited via the HCP protocol on Microsoft Windows XP and Microsoft Windows 2003 through Internet Explorer or Outlook to cause a buffer overflow.
Other versions of Microsoft Windows do not support the HCP protocol and there are therefore no known attack vector. Microsoft states that the vulnerability is not believed to be exploitable on those versions, even though the vulnerable code is included.
Solution:
Microsoft has issued patches:
The patches are available from WindowsUpdate or from:
