OESA-2022-1694 (CVE-2021-22569)

Vulnerability from osv_openeuler – Published: 2022-06-02 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

protobuf security update

Details

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site.

Security Fix(es):

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.(CVE-2021-22569)

Severity

5.5 (Medium)
