1. Summary:

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.

2. Relevant releases/architectures:

Red Hat OpenStack Platform 16.2 - noarch

3. Description:

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)
