Malwarebytes still fixing flaws in antivirus software

The company apologized, saying vulnerabilities are a reality of software development

Malwarebytes said it could take three of four weeks to fix flaws in its consumer product that were found by a Google security researcher.

The company has fixed several server-side vulnerabilities but is still testing a new version of its Anti-Malware product to fix client-side problems, CEO Marcin Kleczynski said in a blog post.

In the meantime, customers can implement a workaround: those using the premium version of Anti-Malware "should enable self-protection under settings to mitigate all of the reported vulnerabilities," he wrote.

Kleczynski apologized, saying vulnerabilities are a reality that come with software development. "While these things happen, they shouldn’t happen to our users," he wrote.

Google researcher Tavis Ormandy uncovered several issues with the Anti-Malware product, including that it doesn't use encryption when downloading fresh signatures.

That opens the possibility for a man-in-the-middle attack, Ormandy said in an advisory. An attacker could potentially replace the signature file.

Ormandy also found three other issues, including a privilege escalation flaw.

He reported the flaws to Malwarebytes in November and gave the company 90 days to fix them before going public.

Ormandy has been analyzing quite a few security products lately and finding alarming problems. Last month, he found a problem in Trend Micro's antivirus software that could be used to steal stored passwords.

Vulnerabilities in security products are especially dangerous since they often have deep access to a computer's operating system.

Dozens of serious vulnerabilities were found last year in antivirus products from vendors including Kaspersky Lab, ESET, Avast, AVG Technologies and Intel Security (formerly McAfee). Security experts have warned for years that flaws in endpoint protection products pose a big risk.

Windows 10 for Business / Dell XPS 13

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 910

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.
