SCA: security update for grpc, grpcio, io.grpc:grpc-protobuf (GHSA-cfgp-2977-2fmm)

high Tenable Cloud Security Plugin ID 421657

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame.
This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables
between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests
from the proxy being interpreted as containing headers from different proxy clients - leading to an
information leak that can be used for privilege escalation or data exfiltration. We recommend upgrading
beyond the commit contained in https://github.com/grpc/grpc/pull/33005
https://github.com/grpc/grpc/pull/33005 (CVE-2023-32731)
