netty-codec-redis: Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...

Netty: [SpdyHttpDecoder] ByteBuf Reference Leak on RST_STREAM Leads to Native Memory Exhaustion

The SpdyHttpDecoder handler in Netty's SPDY-to-HTTP codec allocates a pooled ByteBuf when processing a client-initiated SYNSTREAM frame with FLAGFIN=0, storing the partially-constructed FullHttpRequest in an internal map messageMap to accumulate subsequent DATA frames. When the remote peer sends ...
