Details
It was discovered that Protocol Buffers did not properly validate field
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
issue to cause applications using protobuf to crash, resulting in a denial

Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-1941)
