The Indian Computer Emergency Response Team (CERT-In) has issued a warning regarding high-risk security vulnerabilities in older versions of Google Chrome and Microsoft Edge browsers, which could allow hackers to gain unauthorized access to users’ systems. Specifically, flaws related to “Use after free” in Safe Browsing and Heap buffer overflow in Sync can enable attackers to execute arbitrary code and conduct denial-of-service (DoS) attacks. CERT-In has urged users to update their browsers to the latest versions to mitigate these risks, as both Google and Microsoft have yet to release patches. This incident underscores the critical need for timely software updates to protect user data and privacy, highlighting broader vulnerabilities that can affect cybersecurity on a national scale.
