SUSE CVE-2026-93561

A flaw was found in io.netty/netty-codec-memcache. The Memcache binary protocol codec incorrectly reads keyLength and extrasLength as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted...

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-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...

netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

Important: Red Hat Security Advisory: Red Hat JBoss Enterprise Application Platform 8.1.8 security update

A security update is now available for Red Hat JBoss Enterprise Application Platform 8.1. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...

io.netty/netty-codec-http: Netty RtspDecoder Method-Token Smuggling via Trailing Control Byte

A flaw was found in Netty RtspDecoder. The RtspMethods.valueOf function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol RTSP requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. Th...

io.netty/netty-codec-http: Netty: Denial of Service via unbounded concurrent SPDY streams

A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAXVALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYNSTREAM...

io.netty/netty-codec-http2: HTTP/1 authority-form CONNECT is translated to malformed HTTP/2 CONNECT with Host-controlled :authority

A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leadi...

io.netty/netty-codec-haproxy: Netty: HAProxy PROXY-v2 nested-TLV grandchild ByteBuf reference-count leak (incomplete fix of PR #16881)

A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service DoS for the affected system...

io.netty/netty-codec-http2: HTTP/1 absolute-form Host mismatch is translated to HTTP/2 :authority, overriding the request-target authority

A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2...

netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...

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-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-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...
