Description
Impact
A custom frontend could send a crafted build request that disabled Seccomp and AppArmor protections for the build container, even if the user did not explicitly allow the security.insecure entitlement. Other security measures, like Linux capabilities were still applied to these containers.
Patches
Problem has been fixed in versions v0.31.1+
Workarounds
Only use BuildKit frontends from trusted providers.
NVD description
BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to 0.31.1, a custom frontend could place an invalid SecurityMode value in a crafted build request, and executor/oci/spec_linux.go treated the unsupported value as a non-sandbox mode without requiring the security.insecure entitlement. This disabled Seccomp and AppArmor protections for the build container even though Linux capabilities remained restricted. This issue is fixed in version 0.31.1.
