Since #6610 the fuzzer build has
been broken. This is due to the interaction of rules_foreign_cc external
dependencies and the additional UBSAN blacklist maintained by the
oss-fuzz driver to workaround the fact we don't have
protocolbuffers/protobuf#5901 yet.
Thir PR moves protocolbuffers/protobuf#5901 into
Envoy proper and hence we don't need an UBSAN blacklist in the oss-fuzz
driver anymore.
Risk level: Low
Tesitng: oss-fuzz Docker build.
