Microsoft will, as part of its monthly security patching cycle, launch three new updates on Tuesday. Two patches will be for Windows and at least one of them will be rated as critical. The other update is for Microsoft Office and is also rated critical.
The notice did not specify whether one of the patches will be for Internet Explorer. Microsoft earlier this week offered a workaround for a known flaw in the Web browser that opens the door for intruders to crash IE and to run arbitrary code.
Microsoft said it will also issue a "high-priority" update for Office that is unrelated to security on Tuesday. In addition, that day is tagged for the release of an updated version of the Windows Malicious Software Removal Tool, which detects and removes malicious code placed on computers, the company said.
