docker.io vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in Docker.

Software Description:
- docker.io: reusable Go packages included with Docker

Details:

Cory Snider discovered that Docker incorrectly handled networking packet
encapsulation. An attacker could use this issue to inject internet
packets in established connection, possibly causing a denial of service or
bypassing firewall protections. This issue only affected Ubuntu 22.04 LTS,
Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS. (CVE-2023-28840, CVE-2023-28841,
CVE-2023-28842)

Rory McNamara discovered that Docker incorrectly handled cache in the
BuildKit toolkit. An attacker could possibly use this issue to expose
sensitive information. (CVE-2024-23651)

It was discovered that Docker incorrectly handled parallel operations in
some circumstances, which could possibly lead to undefined behavior.
(CVE-2024-36621, CVE-2024-36623)

Rory McNamara discovered that Docker incorrectly verified file paths during
a certain command in the BuildKit toolkit. An attacker could possibly use
this issue to delete arbitrary files from the system. (CVE-2024-23652)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
  golang-github-docker-docker-dev  20.10.25+dfsg1-2ubuntu1+esm2
                                  Available with Ubuntu Pro
