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.\u00a0<\/p>\n
Affected Scenarios:
\nApplications using bRPC as a Redis client with ChannelOptions.protocol="redis" and receiving replies from an untrusted or faulty Redis server peer.<\/p>\n
How to Fix:
\n1. Upgrade Apache bRPC to 1.18.0.
\n2. Apply the patch from PR https:\/\/github.com\/apache\/brpc\/pull\/3344 .<\/p>\n
Note:
\nAfter applying the fix, Redis replies with array nesting deeper than redis_max_reply_depth are rejected.<\/p>\n","protected":false},"excerpt":{"rendered":"
