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

of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,

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