An update that solves two vulnerabilities and has one security fix can now be
installed.
## Description:
This update for protobuf fixes the following issues:
Refresh fixes:
* CVE-2025-4565: parsing of untrusted Protocol Buffers data containing an
arbitrary number of recursive groups or messages can lead to crash due to
RecursionError (bsc#1244663).
* CVE-2026-0994: `max_recursion_depth` limit can be bypassed when parsing
nested `google.protobuf.Any` messages and lead to the exhaustion of the
Python recursion stack (bsc#1257173).
