The software vendor will address two vulnerabilities in Windows, at least one of which is rated with the most severe classification of 'critical'. The Office productivity suite will get one patch which is also rated 'critical'.
Microsoft is also slated to unveil an update for Office that is not security related but is nonetheless ranked 'high priority'.
The company provides the advance warning in an effort to help IT organisations plan for the monthly patch releases, but does not provide any information other than the software titles that will be fixed.
Microsoft has scheduled a webcast to provide additional information on the fixes on Wednesday 13 July at 11am PDT (7pm GMT).
In common with previous updates, the patches will coincide with an updated version of Microsoft's Malicious Software Removal Tool.
