CVE-2023-2033 is a high-severity security vulnerability affecting Google Chrome and certain Linux distributions. This issue, known as a type confusion in V8, allows a remote attacker to potentially exploit heap corruption through a crafted HTML page. It's important to update your software to protect against potential attacks.
How do I know if I'm affected?
If you're using Google Chrome, Debian Linux, or Fedora, you might be affected by this vulnerability. Specifically, systems running Google Chrome versions up to 112.0.5615.121, Debian Linux 11.0, and Fedora versions 36, 37, and 38 are at risk. This issue could allow a remote attacker to exploit heap corruption through a crafted HTML page. To check if you're affected, verify the version of your software and compare it to the mentioned versions.
What should I do if I'm affected?
If you're affected by this vulnerability, it's crucial to update your software. For Google Chrome users, update to version 112.0.5615.121. Fedora users should update their Chromium browser using the "dnf" command. For Fedora 36, run "su -c 'dnf upgrade --advisory FEDORA-2023-c1741c9724'", and for Fedora 38, use "su -c 'dnf upgrade --advisory FEDORA-2023-911c060ded'".
Is this in CISA’s Known Exploited Vulnerabilities Catalog?
Yes, it is in CISA's Known Exploited Vulnerabilities Catalog. This high-severity issue, known as "Security: \[0-day\] JIT optimisation issue," was added to the catalog on April 11, 2023. Although a specific due date is not mentioned, the vulnerability was subject to a 7-day disclosure deadline. To address this issue, affected software versions need to be updated, and the fix should be backported to earlier versions for extended support.
Weakness enumeration
The weakness enumeration for this vulnerability is categorized as CWE-843, involves a JIT optimization issue that allows attackers to leak a value called "TheHole." This high-severity type confusion issue affects multiple operating systems and has been fixed in recent updates.
