Zero day attack
Disclaimer: Copyright infringement is not intended.
Context:
- Google Chrome has been hit with another zero-day vulnerability which has set the alarm bells ringing among users and cyber experts.
Details:
- The vulnerabilities in Google Chrome are attributed to errors in visuals and angle components leading to use-after-free errors, as well as a heap buffer overflow in WebAudio. These vulnerabilities could allow remote attackers to compromise targeted systems.
- The security alert specifies the versions of Google Chrome that are affected by these vulnerabilities. Users of Google Chrome on Windows, macOS, and Linux systems are urged to take action if they are using versions before 124.0.6367.201/.202 for Windows and Mac, and before 124.0.6367.201 for Linux.
- The severity of Zero-Day Issues: Zero-day vulnerabilities are particularly concerning because they are exploited by attackers before developers have had a chance to address them. This means that users may be unaware of the potential severity of these attacks until they are made public.

“Zero-Day” Definition ●The term “Zero-Day” is used when security teams are unaware of their software vulnerability, and they’ve had “0” days to work on a security patch or an update to fix the issue. “Zero-Day” is commonly associated with the terms Vulnerability, Exploit, and Threat. It is important to understand the difference: ●A Zero-Day Vulnerability is an unknown security vulnerability or software flaw that a threat actor can target with malicious code. ●A Zero-Day Exploit is the technique or tactic a malicious actor uses to leverage the vulnerability to attack a system. ●A Zero-Day Attack occurs when a hacker releases malware to exploit the software vulnerability before the software developer has patched the flaw.
