Update Your Firefox Browser to Fix a Critical Remotely Exploitable Flaw

Mozilla has released an important update for its Firefox web browser to patch a critical vulnerability that could allow remote attackers to execute malicious code on computers running an affected version of the browser.

The update comes just a week after the company rolled out its new Firefox Quantum browser, a.k.a Firefox 58, with some new features like improved graphics engine and performance optimizations and patches for more than 30 vulnerabilities.

According to a security advisory published by Cisco, Firefox 58.0.1 addresses an 'arbitrary code execution’ flaw that originates due to 'insufficient sanitization' of HTML fragments in chrome-privileged documents (browser UI).

Hackers could exploit this vulnerability (CVE-2018-5124) to run arbitrary code on the victim's computer just by tricking them into accessing a link or 'opening a file that submits malicious input to the affected software.'

"A successful exploit could allow the attacker to execute arbitrary code with the privileges of the user. If the user has elevated privileges, the attacker could compromise the system completely," the advisory states.

This could allow an attacker to install programs, create new accounts with full user rights, and view, change or delete data.

However, if the application has been configured to have fewer user rights on the system, the exploitation of this vulnerability could have less impact on the user.

Affected web browser versions include Firefox 56 (.0, .0.1, .0.2), 57 (.0, .0.1, .0.2, .0.3, .0.4), and 58 (.0). The vulnerability has been addressed in Firefox 58.0.1, and you can download from the company's official website.

The issue, which was discovered by Mozilla developer Johann Hofmann, does not affect Firefox browser for Android and Firefox 52 ESR.

Users are recommended to apply the software updates before hackers exploit this issue, and avoid opening links provided in emails or messages if they appear from suspicious or unrecognized sources.

Administrators are also advised to use an unprivileged account when browsing the Internet and monitor critical systems.

iOS 11.3 coming this spring with battery and performance settings, ARKit 1.5, new Animoji

In a sign that Apple will continue to update iOS regularly instead of withholding features for its next major point-zero release, Apple on Wednesday revealed new features coming to an iOS 11.3 update this spring, including the ability to toggle the power management feature for iPhone models with aging batteries. Apple will implement new battery health information and the ability to customize power settings after it was revealed that the company throttles CPU performance on older devices where the battery is deteriorating. Apple's throttling is done to prevent random shutdowns of the device and ensure smooth operation, but some customers took offense to the fact that the slowdowns were occurring without transparency to the user. In a press release issued on Wednesday, Apple said that the iOS 11.3 update this fall will show battery health, and recommend to users if their battery needs to be serviced. The capabilities will be available for iPhone 6 and later. Users will...

DJI Spark vs. Parrot Bebop 2 Which One Is The Best

It's a Parrot vs DJI drone showdown Earlier this year, DJI announced it would be taking on the entry-level, selfie drone market with its Spark . Along with challengers like the Yuneec Breeze , the smallest DJI quadcopter is priced within touching distance of the bigger Parrot Bebop 2 . How do they compare? Weight The Bebop is significantly heavier than the Spark, but that extra weight is an advantage in some ways. More on that in a minute. Battery Parrot has slotted a big battery into the Bebop 2 – the original Bebop had an 1100 mAh unit, compared to the 2700 mAh pack in the latest Bebop 2. That translates to a healthy flight time, too. Flight Time Parrot has a massive advantage over DJI when it comes to flight time. The bigger battery in the Bebop affords it a healthy 25 minute flight time, compared to 16 minutes for the Spark. The heavier Parrot drone is also likely to stand up better to buffeting in high winds. Range Both d...

How To Turn Off Facebook Face Recognition System On App And PC?

When it comes to privacy features, Facebook probably has gone where no company has gone before. It includes unchartered territories like asking people’s naked pictures to help victims of revenge porn. Now, Facebook has introduced another privacy feature that can tell whether someone has uploaded your photo to Facebook’s network. Although it was first announced in December last year, recently the company has reached out Facebook users through their News Feed, notifying them that the face recognition system is being used “for more features.” Analyzing people’s faces and storing them has its benefits. For instance, people can know if someone has uploaded their picture, regardless of whether they’re tagged in it or not. Also, Facebook could tell you whether a stranger is using your photo as their profile picture and help visually impaired users identify people in photographs. Facebook doesn’t store people’s images directly; it creates a blueprint or face...
