CVE-2021-22569

Denial of Service of protobuf-java parsing procedure

Published Jan 7, 2022 CVSS 3.1 · 7.5 High EPSS 1.8% KEV · Not listed
Description
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.
