MS09-060: Vulnerabilities in Microsoft Active Template Library (ATL) ActiveX Controls for Microsoft Office Could Allow Remote Code Execution (973965)
High Nessus Plugin ID 42116
SynopsisArbitrary code can be executed on the remote host through Microsoft Office ActiveX controls.
DescriptionOne 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)
SolutionMicrosoft has released a set of patches for Microsoft Outlook 2002, 2003, and 2007 as well as Visio Viewer 2007.
