description

Docker BuildKit may associate image-layer cache or snapshot state with attacker-controlled content based on inconsistent layer metadata. If an untrusted image is processed by a BuildKit daemon with shared or persistent cache before a trusted build, attacker-supplied code may execute during the later build and access build resources or alter outputs.

mitigation

Upgrade docker to >= v0.33.1 or later.

fixed in >= v0.33.1
