Heap buffer overflow in WebRTC in Google Chrome prior to 103.0.5060.114 allowed a remote attacker to potentially exploit heap corruption via
Noroxi assessment
Priority: Now (action score 86/100)
- CISA has confirmed exploitation in the wild (Aug 25, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Sep 15, 2022.
- Probability of exploitation in the next 30 days: 70.8% (FIRST EPSS); higher than 99.3% 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) 103.0.5060.114-1~deb11u1; chromium (Debian:12) 103.0.5060.114-1; webkit2gtk (Debian:12) 2.36.6-1.
- Mentioned 5 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Patch today or shut off access. Upgrade to chromium (Debian:11) 103.0.5060.114-1~deb11u1; chromium (Debian:12) 103.0.5060.114-1; webkit2gtk (Debian:12) 2.36.6-1 or later.
