Memory Leak

Netty is vulnerable to a Memory Leak. The vulnerability is due to failure to release retained or newly allocated ByteBuf objects when IDN.toASCII or encodeDomainName reject a malformed domain name, where the exception occurs before the buffer is assigned to the DnsRecord content field, allowing...

GHSA-VMR9-J6WF-PMH2 netty-incubator-codec-ohttp: [OHttpServerCodec] Native Direct-Memory Leak on AEAD Decryption Failure Leads to Gateway Denial of Service

The netty-incubator-codec-ohttp library implements Oblivious HTTP OHTTP gateway and client functionality using Netty's ByteBuf memory management. When an OHTTP gateway processes encrypted client requests, it allocates a pooled direct native off-heap ByteBuf to hold the decrypted plaintext before...
