This affects multiple versions prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4. The issue is fixed in these versions.
AI Analysis
Technical Summary
@grpc/grpc-js, a JavaScript implementation of gRPC without C++ addons, has a vulnerability (CWE-248) where invalid compressed messages cause uncaught exceptions leading to process crashes. Versions before 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4 are affected. The vulnerability results in denial of service by crashing the client or server process. The issue is resolved by updating to these fixed versions.
Potential Impact
An attacker can send a specially crafted invalid compressed message to a grpc-node client or server using affected versions, causing the process to crash. This results in denial of service (DoS) but does not impact confidentiality or integrity.
Mitigation Recommendations
Upgrade grpc-node (@grpc/grpc-js) to version 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, or 1.14.4 or later, where the vulnerability is fixed. Patch status is confirmed by the version fixes listed. No other mitigation is indicated.
