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...

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...

undertow: undertow-websockets: Undertow: Pre-Auth DoS on websocket endpoint with @ServerEndpoint class with any @OnMessage method

A flaw was found in Undertow. A remote attacker can cause Out of Memory on websockets endpoint without authentication on any @ServerEndpoint class that has any @OnMessage method. This allows an attacker to cause Denial of Service attack without authentication and using only a standard WebSocket...

wildfly-iiop-openjdk: Missing authentication on EAP's IIOP NameService leads to MITM or DoS

A flaw was found in EAP's IIOP. The listener's NameService would accept bind operations without authentication, allowing an attacker to hijack JNDI lookups and binding them to a malicious ORB, achieving MITM or DoS on further invocations...

undertow-core: Undertow: Denial of Service via WebSocket permessage-deflate processing

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...

org.wildfly.security/wildfly-elytron-asn1: Unbounded Memory Allocation in WildFly Elytron ASN.1 DERDecoder via Crafted DER Payload

A flaw was found in the DERDecoder class within wildfly-elytron-asn1. A remote attacker can exploit this resource exhaustion vulnerability by sending a specially crafted DER Distinguished Encoding Rules payload. The decoder attempts to allocate excessive memory based on an inflated length value...

jboss-remoting: jboss-remoting: integer overflow in MessageReader leads to pre-authentication denial of service

A flaw was found in EAP's jboss-remoting. A remote unauthenticated attacker who can reach :8080 or :9990, or :4447 and complete an Upgrade: jboss-remoting handshake can cause OOM errors that degrade requests server-wide, leading to denial of service...
