Multiple severe, remotely exploitable security vulnerabilities have been found in Chromium, including out-of-bounds memory access in V8, CSS, and Fonts (CVE-2023-4427, CVE-2023-4428, and CVE-2023-4431), and use after frees in Loader and Vulkan (CVE-2023-4429 and CVE-2023-4430). Because of the serious threat these bugs pose to the confidentiality, integrity, and availability of impacted systems and their ease of exploitation, they have all received a National Vulnerability Database severity rating of “High”.
These issues could result in the execution of arbitrary code, denial of service, or information disclosure.
A Chromium security update that mitigates these dangerous flaws has been released. We strongly recommend that all impacted users apply the updates released by Debian, Fedora and openSUSE now to protect against attacks leading to loss of access to critical systems and the compromise of sensitive data.
