An ‘Arbitrary Code Execution’ Flaw
Mozilla released the Firefox update a week after the release of the company’s new Firefox Quantum browser, also known as Firefox 58. The new browser includes an improved graphics engine, as well as performance optimizations and patches for more than 30 browser vulnerabilities.

Cisco released a security advisory that stated this update for Firefox 58.0.1 fixes an ‘arbitrary code execution’ vulnerability.

Could Hackers Get to You?
The vulnerability opens the doors for hackers to run arbitrary code on a victim’s computer that tricks them into opening a file with malware containing malicious code. Cybercriminals could then take control of a user’s privileges and completely compromise their system. They could do everything from installing programs to creating new accounts, to changing or deleting data.

If a user’s configurations offer fewer user rights, the impact on their device could be less harmful. Owners of Firefox 56 (.0, .0.1, .0.2), 57 (.0, .0.1, .0.2, .0.3, .0.4) and 58 (.0) could be affected. You can download the update on the company’s website. The vulnerability was discovered by Mozilla developer Johann Hofmann and it does not affect Firefox browser for Android and Firefox 52 ESR.

How Can Chrome Users Protect Themselves?
If you don’t use Firefox, this update doesn’t apply to you, but Chrome users may have to deal with other vulnerabilities. Google recently released a new update for Chrome in version 64, which includes changes to the browser that should help deal with speculative side-channel browser attacks. These are malicious ways in which hackers try to gain access to a system’s memory.

The biggest lesson here? Always update your browser because important security patches within updates keep your online experiences safer than not.
