netty-codec-http: Netty is vulnerable to request smuggling due to incorrect parsing of chunk extensions

A flaw in Netty’s HTTP/1.1 chunked encoding parser allows newline LF characters in chunk extensions to be incorrectly treated as the end of the chunk-size line instead of requiring the proper CRLF sequence. This discrepancy can be exploited in rare cases where a reverse proxy interprets the same...

netty-handler: Netty: Improper trust manager handling leads to hostname verification bypass

A flaw was found in Netty, a network application framework. This vulnerability allows a remote attacker to bypass hostname verification due to improper handling of user-supplied trust managers. When a client is configured with a plain X.509 Trust Manager X509TrustManager, it fails to perform...

io.netty/netty-resolver-dns: Netty has Insufficient Bailiwick Validation for NS Records

A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...

netty-resolver-dns: Netty: Information disclosure and data manipulation due to improper CNAME record validation

This can lead to an IndexOutOfBoundsException...

netty: io.netty/netty-codec-http: io.netty/netty-codec-http2: Netty: Denial of Service via unbounded memory allocation in HTTP content decompression

A flaw was found in Netty. A remote attacker can bypass the configured decompression limit in the HttpContentDecompressor by sending a specially crafted compressed payload using Brotli br, Zstandard zstd, or Snappy content encodings. This can lead to unbounded memory allocation, resulting in an...

netty: io.netty/netty-codec-compression: io.netty/netty-codec: Netty: Denial of Service via excessive memory allocation in LZ4FrameDecoder

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted LZ4 compressed data stream. This can cause the Lz4FrameDecoder to allocate a large amount of memory up to 32 MB per block before...

netty: Netty: Denial of Service via HTTP/2 CONTINUATION frame flood

A flaw was found in Netty. A remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume...
