Ubuntu 24.10: USN-7161-3 critical: docker unauthorized access

docker.io could allow unintended access to network services. ========================================================================== Ubuntu Security Notice USN-7161-3 April 15, 2025 Docker vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.10 - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: docker.io could allow unintended access to network services Software Description: - 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) Update instructions: The problem can be corrected byupdating your system to the following package versions: Ubuntu 24.10 golang-github-docker-docker-dev 26.1.4+dfsg2-1ubuntu1.1 Ubuntu 24.04 LTS golang-github-docker-docker-dev 20.10.25+dfsg1-2ubuntu1+esm1 Available with Ubuntu Pro Ubuntu 22.04 LTS golang-github-docker-docker-dev 20.10.21-0ubuntu1~22.04.7+esm1 Available with Ubuntu Pro Ubuntu 20.04 LTS golang-github-docker-docker-dev 20.10.21-0ubuntu1~20.04.6+esm1 Available with Ubuntu Pro In general, a standard system update will make all the necessary changes.
