CVE-2024-0519 [HIGH] Google fixes first actively exploited Chrome zero-day of 2024
## Google fixes first actively exploited Chrome zero-day of 2024
## Sergiu Gatlan
Although Google says the security update could take days or weeks to reach all impacted users, it was available immediately when BleepingComputer checked for updates today.
Those who prefer not to update their web browser manually can rely on Chrome to automatically check for new updates and install them after the next launch.
The high-severity zero-day vulnerability ( CVE-2024-0519 ) is due to a high-severity out-of-bounds memory access weakness in the Chrome V8 JavaScript engine, which remote attackers can exploit via a crafted HTML page to gain access to data beyond the memory buffer through heap corruption, providing them access to sensitive information or triggering a crash.

## Google fixes 8th Chrome zero-day exploited in attacks this year
## Sergiu Gatlan
The bug was discovered and reported by Clément Lecigne and Vlad Stolyarov of Google's Threat Analysis Group (TAG), a collective of security experts whose primary goal is to defend Google customers from state-sponsored attacks.
Google's Threat Analysis Group (TAG) frequently discovers zero-day bugs exploited by government-sponsored threat actors in targeted attacks aiming to deploy spyware on the devices of high-risk individuals, including opposition politicians, dissidents, and journalists.
Even though the security update could take days or weeks to reach all users, according to Google, it was available immediately when BleepingComputer checked for updates earlier today.

## 0-days exploited by commercial surveillance vendor in Egypt
Sep 22, 2023
Last week Google’s Threat Analysis Group (TAG), in partnership with The Citizen Lab , discovered an in-the-wild 0-day exploit chain for iPhones. Developed by the commercial surveillance vendor, Intellexa, this exploit chain is used to install its Predator spyware surreptitiously onto a device.
In response, yesterday, Apple patched the bugs in iOS 16.7 and iOS 17.0.1 as CVE-2023-41991, CVE-2023-41992, CVE-2023-41993. This quick patching from Apple helps to better protect users and we encourage all iOS users to install them as soon as possible.
## Exploit delivery via man-in-the-middle (MITM)
