Chrome 103 Update Patches High-Severity Vulnerabilities

Google this week announced a Chrome update that resolves a total of 11 vulnerabilities in the browser, including six reported by external researchers.

Of these, five are use-after-free issues, including four that are considered “high severity.” Use-after-free flaws are triggered when a program does not clear the pointer after freeing memory allocation.

Google this week announced a Chrome update that resolves a total of 11 vulnerabilities in the browser, including six reported by external researchers.

Of these, five are use-after-free issues, including four that are considered “high severity.” Use-after-free flaws are triggered when a program does not clear the pointer after freeing memory allocation.

Such vulnerabilities may lead to the execution of arbitrary code, to denial of service, or the corruption of data but, if they are combined with other issues, can allow for a full system compromise.

In Chrome, use-after-free bugs can often be exploited to escape the browser’s sandbox.

The four high-severity use-after-free vulnerabilities resolved with the latest Chrome 103 update are tracked as CVE-2022-2477, CVE-2022-2478, CVE-2022-2480, and CVE-2022-2481, and impact components such as Guest View, PDF, Service Worker API, and Views.

Google says it has paid $16,000 and $7,500 in bug bounty rewards for the first two flaws, but hasn’t determined the amount to be handed out for the last issue. As per the company’s policy, no reward will be issued for CVE-2022-2480, which was reported by a Google Project Zero researcher.

However, the internet giant did pay $3,000 for CVE-2022-2479, a high-severity issue related to insufficient validation of untrusted input in the File component.

The sixth externally reported vulnerability addressed with this Chrome update is CVE-2022-2163, a low-severity use-after-free issue in Cast UI and Toolbar, which earned the reporting researcher a $7,000 bug bounty reward.

Google makes no mention of any of these vulnerabilities being exploited in the wild.

The latest Chrome update is currently rolling out to Windows, Mac, and Linux users as version 103.0.5060.134.
