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.

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.

Windows 8 and Windows Server 2012 file information notesImportant 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:

    Version

    Product

    Milestone

    Service branch

    6.2.920 0.16xxx

    Windows RT, Windows 8 and Windows Server 2012

    RTM

    GDR

    6.2.920 0.20xxx

    Windows RT, Windows 8 and Windows Server 2012

    RTM

    LDR

  • 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. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
