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)
