CVE-2023-7024: Heap buffer overflow in WebRTC in Google Chrome prior to 120.0.6099.129 allowed a remote attacker to potentially exploit heap corruption via

Noroxi assessment

Priority: This week (action score 67/100)

  • CISA has confirmed exploitation in the wild (Jan 2, 2024). Remediation deadline for US federal agencies: Jan 23, 2024.
  • Probability of exploitation in the next 30 days: 6.6% (FIRST EPSS); higher than 93.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: chromium (Debian:11) 120.0.6099.129-1~deb11u1; chromium (Debian:12) 120.0.6099.129-1~deb12u1; chromium (Debian:13) 120.0.6099.129-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to chromium (Debian:11) 120.0.6099.129-1~deb11u1; chromium (Debian:12) 120.0.6099.129-1~deb12u1; chromium (Debian:13) 120.0.6099.129-1 or later.
