  Vulnerability details:

  PowerPoint Malformed Object Pointer Vulnerability - CVE-2006-3435:

  A remote code execution vulnerability exists in PowerPoint. An attacker could
  exploit this vulnerability when PowerPoint parsed a file that included a 
  malformed object pointer.

  If a user were logged on with administrative user rights, an attacker who 
  successfully exploited this vulnerability could take complete control of an 
  affected system. An attacker could then install programs; view, change, or 
  delete data; or create new accounts with full user rights. Users whose 
  accounts are configured to have fewer user rights on the system could be less
  affected than users who operate with administrative user rights.

  PowerPoint Malformed Data Record Vulnerability - CVE-2006-3876:

  A remote code execution vulnerability exists in PowerPoint. An attacker could
  exploit this vulnerability when PowerPoint parsed a file that included a 
  malformed Data record.

  If a user were logged on with administrative user rights, an attacker who 
  successfully exploited this vulnerability could take complete control of 
  an affected system. An attacker could then install programs; view, change,
  or delete data; or create new accounts with full user rights. Users whose
  accounts are configured to have fewer user rights on the system could be less
  affected than users who operate with administrative user rights.

  PowerPoint Malformed Record Memory Corruption Vulnerability - CVE-2006-3877:

  A remote code execution vulnerability exists in PowerPoint and could be 
  exploited when PowerPoint opened a specially crafted file. Such a file might
  be included in an e-mail attachment or hosted on a malicious web site. An 
  attacker could exploit the vulnerability by constructing a specially crafted
  PowerPoint file that could allow remote code execution.

  If a user were logged on with administrative user rights, an attacker who 
  successfully exploited this vulnerability could take complete control of an
  affected system. An attacker could then install programs; view, change, or 
  delete data; or create new accounts with full user rights. Users whose 
  accounts are configured to have fewer user rights on the system could be less
  affected than users who operate with administrative user rights.

  PowerPoint Malformed Record Vulnerability - CVE-2006-4694:

  A remote code execution vulnerability exists in PowerPoint and could be
  exploited when PowerPoint opened a specially crafted file. Such a file might
  be included in an e-mail attachment or hosted on a malicious web site. An 
  attacker could exploit the vulnerability by constructing a specially crafted
  PowerPoint file that could allow remote code execution.

  If a user were logged on with administrative user rights, an attacker who
  successfully exploited this vulnerability could take complete control of an
  affected system. An attacker could then install programs; view, change, or 
  delete data; or create new accounts with full user rights. Users whose 
  accounts are configured to have fewer user rights on the system could be less
  affected than users who operate with administrative user rights.
