io.netty/netty-codec-compression: Netty: Infinite loop in netty-codec-compression (bzip2)

A flaw was found in the netty-codec-compression component of Netty. This vulnerability, caused by a logic error in the bzip2 decoder, allows a remote attacker to send specially crafted bzip2-compressed data. Processing this malformed data can trigger an infinite loop, causing the decoder thread t...

io.netty/netty-codec-http: Netty: Memory exhaustion in netty-codec-http (decompression bomb)

A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to...

io.netty/netty-codec-dns: Netty: Denial of Service via Memory Leak in DNS Record Decoder with Malformed Domain Names

A flaw was found in Netty, an asynchronous network application framework. When processing malformed domain names in DNS packets, the DNS record decoder fails to release allocated memory. This vulnerability allows an unauthenticated remote attacker to incrementally leak direct memory, eventually...

io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...

io.netty/netty-handler-ssl-ocsp: Netty: Certificate revocation bypass via OCSP response replay attack

A flaw was found in Netty. The OcspClient component fails to validate that the Certificate ID in an Online Certificate Status Protocol OCSP response matches the requested Certificate ID. This vulnerability allows a remote attacker to bypass certificate revocation checks by presenting a legitimate...

netty: io.netty/netty-codec-http: Netty: Denial of Service via memory exhaustion in SPDY-to-HTTP codec

A flaw was found in Netty. A remote attacker can exploit a vulnerability in the SpdyHttpDecoder handler of Netty's SPDY-to-HTTP codec. When processing a client-initiated SYNSTREAM frame, the decoder fails to release allocated memory if the stream is reset or content limits are exceeded. This...

io.netty/netty-codec-haproxy: Netty codec-haproxy: Denial of Service via crafted PROXY protocol v2 message

A flaw was found in Netty's codec-haproxy module. A remote attacker could exploit a vulnerability in the HAProxyMessageDecoder by sending a specially crafted PROXY protocol v2 message. This leads to unbounded buffer accumulation, causing a denial of service DoS due to memory exhaustion...

io.netty/netty-codec-http: Netty: Security control bypass allows unauthorized requests via null origin header

A flaw was found in Netty, a network application framework. A remote attacker can bypass security controls in the CorsHandler component by sending a specially crafted request with a null origin header. This bypasses the intended access restrictions, allowing unauthorized requests to reach the...

io.netty/netty-handler: Netty: TLS hostname verification bypass via OpenSSL client path misconfiguration

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...
