Summary
Red Hat Security Advisory: Red Hat OpenStack Platform 16.2.4 (protobuf) security update

Notes

Topic
An update for protobuf is now available for Red Hat OpenStack Platform 16.2.4 (Train). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats. Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. You can even update your data structure without breaking deployed programs that are compiled against the old format. This package contains Protocol Buffers compiler for all programming languages and C++ headers and Static libraries for Protocol Buffers built with optimize_for = LITE_RUNTIME. Security Fix(es): * Incorrect parsing of nullchar in the proto symbol leads to Nullptr dereference (CVE-2021-22570)
