      "title": "Apache bRPC: Stack Exhaustion via Unbounded Recursion in Redis Reply Parser",
      "summary": "Uncontrolled recursion in the Redis reply parser in Apache bRPC < 1.18.0 allows a remote Redis server peer to crash a bRPC Redis client process by returning a deeply nested RESP array reply. The parser recursed once for each nested array level without enforcing a depth limit. The fix adds a configurable Redis reply depth limit with default value 128 and rejects replies exceeding that limit. \n\nAffected Scenarios:\nApplications using bRPC as a Redis client with ChannelOptions.protocol=\"redis\" and receiving replies from an untrusted or faulty Redis server peer.\n\nHow to Fix:\n1. Upgrade Apache bRPC to 1.18.0.\n2. Apply the patch from PR  https://github.com/apache/brpc/pull/3344 .\n\nNote:\nAfter applying the fix, Redis replies with array nesting deeper than redis_max_reply_depth are rejected.",
