Memory leak in Oleaut32.dll on a Windows 7 SP1, Windows Server 2008 R2 SP1, Windows 8, Windows Server 2012, Windows 8.1 or Windows Server 2012 R2-based COM server

Symptoms
Consider the following scenario:
  • You have an out-of-process COM server that is running Windows 7 Service Pack 1 (SP1), Windows Server 2008 R2 SP1, Windows 8, Windows Server 2012, Windows 8.1 or Windows Server 2012 R2. 
  • You run an application that is based on Microsoft COM technology on a client computer.
  • The application makes a COM call to the COM server. The client computer uses an interface to pass a SAFEARRAY user-defined data type to the COM server.
In this scenario, a memory leak occurs in Oleaut32.dll on the COM server.
Cause
This issue occurs because Oleaut32.dll does not work correctly when the system frees allocated memory.

Windows 8 and Windows Server 2012 file information notes

Important Windows 8 hotfixes and Windows Server 2012 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8/Windows Server 2012" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.2.920 0.16xxxWindows RT, Windows 8 and Windows Server 2012RTMGDR
    6.2.920 0.20xxxWindows RT, Windows 8 and Windows Server 2012RTMLDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 8 and for Windows Server 2012" section.
