Security Vulnerabilities
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's IP defragmentation tracker lookup did not verify that an existing tracker used the same IP address family as the packet being processed. Under crafted fragmented IPv4/IPv6 traffic, an IPv6 fragment could be associated with an IPv4 defragmentation tracker. This can lead to a remote packet-triggered crash and denial of service when Suricata performs the relevant defragmentation. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, if using Suricata as an IDS with AF_PACKET, enabling AF_PACKET's `defrag` option may prevent Suricata from seeing such fragmented packets.

IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to a security bypass due to improper authentication controls. A local attacker could exploit this vulnerability to escalate privileges and gain unauthorized access to protected resources.

IBM Langflow OSS 1.0.0 through 1.11.5 Langflow could allow an authenticated attacker to access sensitive files belonging to other users due to improper access control in the File/Read File component. When executing flows through the /api/v1/run/advanced/{flow_id} endpoint, the application allows component inputs to reference storage paths using arbitrary user or flow identifiers without verifying ownership. An attacker with low‑privileged authenticated access can supply a crafted file path pointing to another user’s storage namespace, causing the backend to read and return the contents of files uploaded by other users. This vulnerability bypasses intended authorization checks enforced by the file management API and may result in unauthorized disclosure of sensitive user data.

IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to server-side request forgery (SSRF) that could allow a remote, unauthenticated attacker to cause the server to send outbound requests to arbitrary endpoints.

IBM Langflow OSS 1.0.0 through 1.11.5 Langflow could allow an unauthenticated attacker to execute arbitrary code and access or modify chat sessions through publicly shared MCP project endpoints due to improper enforcement of public-flow security restrictions and session isolation controls.

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;)`.

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, a crafted rule using mixed-case frame syntax could trigger a heap buffer overflow while Suricata is loading signatures. The issue is reached during rule parsing/loading rather than by network traffic alone. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, preprocess rules to check that frames are all lowercase and/or only load trusted rulesets.

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's inspection-buffer helper could leave an inspection pointer referencing freed memory after a chained transform caused the backing buffer to be reallocated. The issue is reached during a specific network traffic processing, and requires a specific but not malicious rule. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, avoid rules that chain `dotprefix` transform after another one.

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, when certain detection transforms are chained, the decompress transform pipeline could read from an inspection buffer after it had been reallocated and freed. The issue is reached during network traffic processing, but requires a malicious rule as Suricata will crash whatever the traffic. Version 8.0.5 contains a fix. As a workaround, avoid rules that chain `gunzip` or `zlib_deflate` with `max-size` bigger than 4096 after another transform.
