Discrepancy between Microsoft Update Catalog and Microsoft Security BulletinSearch?

Dear Members:

This is in relation to Windows Server 2008 R2 Service Pack-1.

Microsoft Update Catalog indicates that Patch No. KB2876331 (MS13-089) has been superseded by Patch No.KB2993651 (MS14-045).

But when we look up the Microsoft Security Bulletin for MS14-045, this makes NO mention of superseding the above patch for MS13-089.

Even if we look up Microsoft’s BulletinSearch spreadsheet, it makes no mention of MS14-045 superseding the Patch No. KB2876331 (MS13-089).

Could one you please clarify the above apparent discrepancy?

Thank you very much for your time and interest.

With best regards,

Ganesh
