How to fix?

Upgrade Ubuntu:22.10 protobuf to version 3.12.4-1ubuntu7.22.10.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream protobuf package and not the protobuf package as distributed by Ubuntu. See How to fix? for Ubuntu:22.10 relevant fixed versions and status.

A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3, 3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions for 3.16 and 3.17 are no longer updated.
