Descripción técnica

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5,IKEv2 parser state could grow without bounds while storing client transforms. Repeated crafted UDP traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Versions 7.0.16 and 8.0.5 fix the issue. Some workarounds are available. Disable IKE application-layer parsing if it is not needed. Alternatively, use a rule to bypass ike flows after the first packets like `alert ike any any -> any any (sid: 2; flow.pkts_toserver: > 256; bypass; noalert;)`.

———Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, LDAP transaction state could store an unbounded number of responses. Because LDAP can be processed over UDP, crafted traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Version 8.0.5 contains a fix. As a workaround, disable LDAP application-layer parsing where it is not required. Alternatively, use a rule like `alert ldap any any -> any any (sid: 1; ldap.responses.count: >1024; bypass;)`.7h CVE-2026-457667.5 ALT

———Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, certain NFS parser state structures were insufficiently bounded. Crafted NFS traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable NFS application-layer parsing if it is not needed.7h CVE-2026-457657.5 ALT

———Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, DNP3 reassembly could buffer data without sufficient parser-level bounds. Crafted DNP3 traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable DNP3 (which is not enabled by default) if it is not needed, and/or define a limited `stream.reassembly.depth` (0 or absent is unlimited).7h CVE-2026-457597.5 ALT

———Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, Suricata could repeatedly perform expensive parsing of large HTTP `Content-Disposition` headers during HTTP response body processing. Crafted HTTP traffic could cause excessive CPU usage and denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, use a rule like `alert http1 any any -> any any (sid: 1; http.request_header; content: "Content-Disposition:"; startswith; bsize: > 8192; bypass;)`.8h CVE-2026-93385.3 MED

———IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to trigger excessive resource consumption, potentially leading to reduced availability of the affected service.10h CVE-2026-871066.5 MED

———Consul and Consul Enterprise are vulnerable to a denial of service in the native RPC listener that may allow an authenticated client to exhaust server memory before ACL authorization is evaluated. A client that can complete the internal RPC mTLS handshake may exploit this issue without holding a valid ACL token. This vulnerability (CVE-2026-87106) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4.10h
