Dist Ubuntu Esm H88
The Debian Security Advisory DSA-4862-1 outlines important kernel updates for several Debian versions, targeting severe vulnerabilities.
Several security issues were fixed in Docker.

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)
