This certificate bundle, a dependency of these products (Dependency on Vulnerable Third-Party Component, CWE-1395), could allow an attacker to intercept or modify TLS-protected traffic via Signature Spoofing by Key Theft (CAPEC-474). The certificate bundle includes root certificate authorities that signed eight eMudhra intermediate certificate authorities whose private keys are compromised. Anyone with these keys can issue a certificate for any host name that these products accept as trusted. Exploitation requires an attacker in a network position between the product and the remote party, who presents a certificate issued with one of the compromised keys.\n\n## Affected\n\n- `docker_images >= 8.0.0 <= 8.19.23`\n- `docker_images >= 9.0.0 <= 9.4.8`\n- `docker_images >= 9.5.0 <= 9.5.5`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":40.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
