CVE-2021-22569, GHSA-wrvw-hg22-4m67, GMS-2022-1
gem/google-protobuf
Denial of Service
An issue in protobuf-java (JRuby gem) allowed the interleaving of com.google.protobuf.UnknownFieldSet
fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. We recommend upgrading libraries beyond the vulnerable versions.
All versions before 3.19.2
Upgrade to version 3.19.2 or above.
