Description of the vulnerability
The Visual Studio development environment provides the ATL (Active Template Library) library, which is used to create ActiveX, and contains several vulnerabilities described in VIGILANCE-VUL-8895. Several ActiveX produced by Microsoft are linked to ATL, and are thus also impacted by these vulnerabilities. Moreover, some products are linked to a private version of ATL and are impacted by vulnerabilities which do not impact the public version of Visual Studio.
The Microsoft Video ActiveX is linked to a private version of ATL, which contains a vulnerability in the CComVariant::ReadFromStream() function. This vulnerability leads to code execution, and was described in VIGILANCE-VUL-8841. [severity:4/4; BID-35558, CERTA-2009-AVI-278, CERTA-2009-AVI-325, CVE-2008-0015, VU#180513]
The Microsoft Video ActiveX is linked to a private version of ATL, which contains a vulnerability in the IPersistStreamInit::Load() function. This vulnerability leads to code execution. [severity:4/4; CVE-2008-0020]
Several Microsoft ActiveX are linked to the public version of ATL, and are thus impacted by the CVE-2009-0901 vulnerability described in VIGILANCE-VUL-8895, which can be used to execute code. [severity:4/4; CERTA-2009-AVI-300, CERTA-2009-AVI-440, CERTA-2009-AVI-516, CERTA-2010-AVI-083, CVE-2009-0901]
Several Microsoft ActiveX are linked to the public version of ATL, and are thus impacted by the CVE-2009-2493 vulnerability described in VIGILANCE-VUL-8895, which can be used to instanciate all ActiveX (even those with the Kill Bit). [severity:4/4; CERTA-2009-AVI-435, CERTA-2009-AVI-538, CVE-2009-2493]
Several Microsoft ActiveX are linked to a private version of ATL, which contains a vulnerability in the handling of Variants, and leads to code execution. [severity:4/4; BID-35982, CVE-2009-2494]
An attacker can therefore create an HTML page containing one of these ActiveX in order to execute code on victim's computer.
