com.google.protobuf.UnknownFieldSet in protobuf-java. An attacker could
possibly use this issue to perform a denial of service attack. This issue
only affected protobuf Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2021-22569)

It was discovered that Protocol Buffers did not properly parse certain
symbols. An attacker could possibly use this issue to cause a denial of
service or other unspecified impact. (CVE-2021-22570)

It was discovered that Protocol Buffers did not properly manage memory when
parsing specifically crafted messages. An attacker could possibly use this
