Microsoft Releases Rare Bug Fix Off of Regular Patch Schedule

Microsoft Releases Rare Bug Fix Off of Regular Patch Schedule

Most of us like to take matters into our own hands, almost to a point where we might refer to ourselves as control freaks. So, when it comes to letting other people or even our own devices update themselves, we tend to click “remind me later” or “don’t ask me again”. Patches however, are a crucial task in the computing era. Keeping everything up-to-date aids your business in staying one step ahead of lurking threats. Recently, Microsoft announced that it had two major security updates which required emergency patches. 

The two vulnerabilities were patched off of Microsoft’s typical “patch Tuesday” due to the urgency. Most Microsoft patches are released on the second Tuesday of the month. The fact that these two were released ahead of time might seem like an insignificant occurrence, but the reality is this event is a major red flag.

Internet Explorer Zero-Day

The most significant patch was for a zero-day vulnerability that was found in Internet Explorer. It may be hard to believe, but people are indeed still using this antique browser to surf the web. The term zero-day suggests that the vulnerability that was discovered, had already been exploited by ill-minded cybercriminals. 

While not much information has been released on the event, Microsoft did call it a remote code execution exploit that, if accessed, could have given a user control of another user’s account. The attack requires phishing someone who is exploring the internet on Internet Explorer, and luring them onto a malicious website. Once there, an attacker would be able to gain access over the victim. 

Internet Explorer is such a forgotten browser that the event did not spark a lot of controversy. This is largely due to the fact that Internet Explorer makes up just two percent of the active market share. However, for the relatively small amount of users that continue to surf, an event like this is still a huge disaster. 

Microsoft Defender DOS Bug

The second patch that Microsoft expedited was a denial of service vulnerability in Microsoft Defender. The antivirus program comes standard in all Windows 10 PCs, and truly is the core of Windows 10’s sterling security record. 

The bug that was discovered wasn’t necessarily obvious, or easily exploitable. In order to do so, the attacker would need the ability to read, understand, and write code. Doing so would allow them to disable Windows Defender components, giving the attacker access. This would give them free rein to do whatever malicious act they chose to deploy.
