Impact
A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic.
Patches
The issue has been fixed in v0.12.5
Workarounds
Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the #syntax line on your Dockerfile, or with --frontend flag when using buildctl build command.
