Message-ID: <56BB8F22.5070008@securify.nl> Date: Wed, 10 Feb 2016 20:27:30 +0100 From: "Securify B.V." <lists@...urify.nl> To: bugtraq@...urityfocus.com Subject: BDA MPEG2 Transport Information Filter DLL side loading vulnerability ------------------------------------------------------------------------ BDA MPEG2 Transport Information Filter DLL side loading vulnerability ------------------------------------------------------------------------ Yorick Koster, September 2015 ------------------------------------------------------------------------ Abstract ------------------------------------------------------------------------ A DLL side loading vulnerability was found in the BDA MPEG2 Transport Information Filter that ships with Windows Vista. This issue can be exploited by loading the filter as an embedded OLE object. When instantiating the object Windows will try to load the DLL ehTrace.dll from the current working directory. If an attacker convinces the user to open a specially crafted (Office) document from a directory also containing the attacker's DLL file, it is possible to execute arbitrary code with the privileges of the target user. This can potentially result in the attacker taking complete control of the affected system. ------------------------------------------------------------------------ See also ------------------------------------------------------------------------ - CVE-2016-0041 - MS16-014: Security Update for Microsoft Windows to Address Remote Code Execution (3134228) ------------------------------------------------------------------------ Tested versions ------------------------------------------------------------------------ This issue was successfully verified on Windows Vista + Office 2010 32-bit. ------------------------------------------------------------------------ Fix ------------------------------------------------------------------------ Microsoft released MS16-014 that fixes this vulnerability. ------------------------------------------------------------------------ Details ------------------------------------------------------------------------ https://www.securify.nl/advisory/SFY20150906/bda_mpeg2_transport_information_filter_dll_side_loading_vulnerability.html
