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)
