USN-7161-1: Docker vulnerabilities
First published: Mon Dec 16 2024(Updated: )
Yair Zak discovered that Docker could unexpectedly forward DNS requests from internal networks in an unexpected manner. An attacker could possibly use this issue to exfiltrate data by encoding information in DNS queries to controlled nameservers. This issue was only addressed in Ubuntu 24.04 LTS. (CVE-2024-29018) Cory Snider discovered that Docker did not properly handle authorization plugin request processing. An attacker could possibly use this issue to bypass authorization controls by forwarding API requests without their full body, leading to unauthorized actions. (CVE-2024-41110)
