Elixir grpc_server 1.0.6 Fixes Streaming Memory Exhaustion
Tech GuruQuick Answer
Identify grpc_server endpoints exposing client-streaming or bidirectional RPCs. Update affected 1.0.x packages to 1.0.6, validate message-size limits and recovery, and retain dependency and regression-test evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Record grpc_server dependency versions, deployed releases, exposed client-streaming or bidirectional RPC methods, request limits and service owners. Match the documented versions and feature prerequisites to the deployment. >=1.0.0 and <1.0.6, when streaming RPC methods are exposed Upgrade affected grpc_server 1.0.x dependencies to 1.0.6 and redeploy the service, or apply the project fix identified in the EEF record through the supported maintenance process. Verify the deployed dependency and streaming message limits, test normal RPC traffic and controlled oversized-message rejection, and retain build, memory-monitoring and recovery evidence.

What Changed
The Erlang Ecosystem Foundation reports that streaming RPC requests can exhaust memory in Elixir grpc_server before 1.0.6; unary limits do not establish protection for streaming calls.
What To Validate Now
- Inventory. Record grpc_server dependency versions, deployed releases, exposed client-streaming or bidirectional RPC methods, request limits and service owners.
- Establish applicability. Match the documented versions and feature prerequisites to the deployment. >=1.0.0 and <1.0.6, when streaming RPC methods are exposed
- Remediate. Upgrade affected grpc_server 1.0.x dependencies to 1.0.6 and redeploy the service, or apply the project fix identified in the EEF record through the supported maintenance process.
- Validate. Verify the deployed dependency and streaming message limits, test normal RPC traffic and controlled oversized-message rejection, and retain build, memory-monitoring and recovery evidence.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Unary request limits do not establish protection for streaming RPCs.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
