ADVISORIES

GEM

grpc

SEVERITY

CVSS v3.x: 5.3 (Medium)

PATCHED VERSIONS

  • >= 1.53.0

DESCRIPTION

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.
