    Stop Worrying and Start Isolating – 4th Zero-Day Exploit Discovered in May 2024

    By BUFFERZONE Team, 3/06/2024

    Tags: Isolation, Safe Workspace®, Safe Browser, Zero-day

    In today’s digital landscape, the dangers posed by browser exploits are more pressing than ever, highlighting the critical need for sophisticated application isolation as a preventive solution. On Thursday, Google released updates to fix a high-severity security flaw (Zero-day) in its Chrome browser, which has been exploited in the wild.

    The vulnerability, CVE-2024-5274, is rooted as a bug in the V8 JavaScript and WebAssembly engine.

    The vulnerabilities occur when a program accesses a resource using an incompatible type, leading to severe consequences such as out-of-bounds memory access, system crashes, and arbitrary code execution by attackers.

    This incident marks the fourth zero-day vulnerability that Google has addressed since the beginning of the month, following fixes for CVE-2024-4671, CVE-2024-4761, and CVE-2024-4947.

    These frequent and critical patches underscore the need for robust application isolation strategies to safeguard against such sophisticated threats since detection cannot alert in time to prevent this initial attack phase.

    Staying Safe in the Digital World

    To defend against new browser threats, individuals and organizations must implement proactive security measures, as detecting abnormal behavior is often too late when dealing with zero-day attacks. That is why we developed BUFFERZONE® Safe Workspace®, a set of zero-trust solutions including Safe Mail, NoCloud™ Artificial Intelligence (AI) Anti-Phishing, SafeBridge® Content Disarm and Reconstruction (CDR), and Safe Browser. Safe Browser is a secure browsing solution that separates your existing Browser from trusted enterprise resources, providing isolation and protection.

    Safe Mail is a Microsoft Outlook plugin that utilizes BUFFERZONE® Safe Workspace® to open links and attachments safely within a secure virtual container. This container isolates browsing and file activity, safeguarding your computer from evasive attacks. This sophisticated Zero-day exploit attack is contained and will not be able to penetrate the organization and steal sensitive data. Furthermore, the isolation restricts lateral movement within the organization, and your existing security controls can scan the isolated zone, adding extra layers of protection.


    Browser threats are hazardous, and attackers always find innovative ways to bypass detection. By isolating threats and adding prevention capabilities to your existing detection solution with an intelligent phishing detection solution, the organization achieves the highest level of security and keeps IT simple.
