IE, Outlook, Excel flaws patched
Microsoft has issued patched to fix vulnerabilities in three of its software applications.
Four security patches were released in all, three of which were rated 'critical'.
Vulnerabilities in email application Outlook, spreadsheet software Excel and browser Internet Explorer have all been fixed. A further patch was released to mend a flaw in the Windows operating system, though this vulnerability wasn't rated as important.
The Internet Explorer flaw affects several versions of the browser including IE7, released late last year. So far, IE7 has proved to be a good deal more secure than its predecessor, so Microsoft will hope not to find too many more flaws in IE7 in the future.
The way Internet Explorer works with the Vista operating system, essentially within a sandboxed environment, suggests these hopes may not be in vain.
Industry-watchers had expected to see eight patches released by Microsoft yesterday, though only four emerged, suggesting that some had failed to meet quality control standards before the release deadline.
Microsoft regularly issues patches for its software products on the second Tuesday of every month.
