Arbitrary code can be executed on the remote host through Microsoft
Office ActiveX controls.
One or more ActiveX controls included in Microsoft Outlook or Visio
and installed on the remote Windows host was compiled with a version
of Microsoft Active Template Library (ATL) that is affected by
potentially several vulnerabilities :
- An issue in the ATL headers could allow an attacker to
force VariantClear to be called on a VARIANT that has
not been correctly initialized and, by supplying a
corrupt stream, to execute arbitrary code.
- Unsafe usage of 'OleLoadFromStream' could allow
instantiation of arbitrary objects which can bypass
related security policy, such as kill bits within
Internet Explorer. (CVE-2009-2493)
- An attacker who is able to run a malicious component or
control built using Visual Studio ATL can, by
manipulating a string with no terminating NULL byte,
read extra data beyond the end of the string and thus
disclose information in memory. (CVE-2009-2495)
