Ubuntu Security Notice USN-7161-1
December 16, 2024
Docker vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in Docker.
Software Description:
- docker.io-app: Linux container runtime
- docker.io: Linux container runtime
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 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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.10
docker.io 26.1.3-0ubuntu1.1
Ubuntu 24.04 LTS
docker.io 26.1.3-0ubuntu1~24.04.1+esm1
Available with Ubuntu Pro
Ubuntu 18.04 LTS
