CVE-2023-32732: Fedoraproject Fedora

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy and a gRPC server: a base64 encoding error for `-bin` suffixed headers will result in a disconnection by the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyond the commit in  https://github.com/grpc/grpc/pull/32309 https://www.google.com/url
