USN-7161-3: Docker vulnerability
15 April 2025

docker.io could allow unintended access to network services

Releases

• Ubuntu 24.10
• Ubuntu 24.04 LTS
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• docker.io - reusable Go packages included with Docker

Details
USN-7161-1 and USN-7161-2 fixed CVE-2024-41110 for source package
docker.io in Ubuntu 18.04 LTS and for source package docker.io-app in
Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 24.10.
This update fixes it for source package docker.io in Ubuntu 20.04 LTS,
Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 24.10. These updates only
address the docker library and not the docker.io application itself, which
was already patched in the previous USNs (USN-7161-1 and USN-7161-2).

Original advisory details:
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 for the source
package docker.io-app 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. This issue was only addressed
for the source package docker.io-app in Ubuntu 24.10 and
Ubuntu 24.04 LTS, and the source package docker.io in Ubuntu 18.04 LTS.
(CVE-2024-41110)
