CVE-2021-22569 (GCVE-0-2021-22569)

Vulnerability from cvelistv5 – Published: 2022-01-07 00:00 – Updated: 2025-04-21 13:57
VLAI
Title
Denial of Service of protobuf-java parsing procedure
Summary
An issue in protobuf-java 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.
