Microsoft says reported IE 7 bug not in browser

Microsoft says that a reported IE 7 bug lies not in the browser, but in Outlook Express

A flaw that research firm Secunia claimed to have discovered in Internet Explorer 7 just hours after its unveiling is not a browser bug after all, Microsoft said Thursday.

Instead, the problem lies in a component of Microsoft's Outlook Express e-mail client, which can be triggered by the browser.

The flaw could be used in phishing attacks to read sensitive information from the IE browser, Secunia said. The Danish security firm first reported the problem with the IE 6 browser in April and found that it could be reproduced on IE 7 as well. Secunia's advisory can be found here.

Secunia does not consider the problem to be critical, but it was widely reported because its discovery came so soon after IE 7's launch.

"These reports are technically inaccurate," wrote Christopher Budd, a security program manager with Microsoft, in a Thursday blog posting. "The issue concerned in these reports is not in Internet Explorer 7 (or any other version) at all."

One security researcher said he was surprised that Microsoft had apparently not informed Secunia of the nature of this bug back in April, when it was first disclosed.

"They reported this in ... April," said Secure Network SRL Chief Technology Officer Stefano Zanero in an instant message interview. "Microsoft should have investigated then and should have already reported the bug to be not in IE."

"How was Secunia supposed to know?" he asked.

A spokesman with Microsoft's public relations agency could not say what response Microsoft had made to Secunia's first report of the problem back in April. "All I can tell you is that the ... blog is the latest and greatest information we have to share," he said.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
