2025-04-10 | CVE-2025-29915 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. The AF_PACKET defrag option is enabled by default and allows AF_PACKET to re-assemble fragmented packets before reaching Suricata. However the default packet size in Suricata is based on the network interface MTU which leads to Suricata seeing truncated packets. Upgrade to Suricata 7.0.9, which uses better defaults and adds warnings for user configurations that may lead to issues. | Suricata | 7.5 | ||
2025-04-10 | CVE-2025-29916 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Datasets declared in rules have an option to specify the `hashsize` to use. This size setting isn't properly limited, so the hash table allocation can be large. Untrusted rules can lead to large memory allocations, potentially leading to denial of service due to resource starvation. This vulnerability is fixed in 7.0.9. | Suricata | 5.5 | ||
2025-04-10 | CVE-2025-29917 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. The bytes setting in the decode_base64 keyword is not properly limited. Due to this, signatures using the keyword and setting can cause large memory allocations of up to 4 GiB per thread. This vulnerability is fixed in 7.0.9. | Suricata | 5.5 | ||
2025-04-10 | CVE-2025-29918 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. A PCRE rule can be written that leads to an infinite loop when negated PCRE is used. Packet processing thread becomes stuck in infinite loop limiting visibility and availability in inline mode. This vulnerability is fixed in 7.0.9. | Suricata | 5.5 | ||
2024-04-03 | CVE-2024-28870 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine developed by the OISF and the Suricata community. When parsing an overly long SSH banner, Suricata can use excessive CPU resources, as well as cause excessive logging volume in alert records. This issue has been patched in versions 6.0.17 and 7.0.4. | Suricata | 7.5 | ||
2023-04-06 | CVE-2020-19678 | Directory Traversal vulnerability found in Pfsense v.2.1.3 and Pfsense Suricata v.1.4.6 pkg v.1.0.1 allows a remote attacker to obtain sensitive information via the file parameter to suricata/suricata_logs_browser.php. | Suricata, Pfsense, Suricata_package | 7.5 | ||
2024-02-26 | CVE-2024-23836 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 6.0.16 and 7.0.3, an attacker can craft traffic to cause Suricata to use far more CPU and memory for processing the traffic than needed, which can lead to extreme slow downs and denial of service. This vulnerability is patched in 6.0.16 or 7.0.3. Workarounds include disabling the affected protocol app-layer parser in the yaml and reducing the... | Fedora, Suricata | 7.5 | ||
2024-02-26 | CVE-2024-23839 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.3, specially crafted traffic can cause a heap use after free if the ruleset uses the http.request_header or http.response_header keyword. The vulnerability has been patched in 7.0.3. To work around the vulnerability, avoid the http.request_header and http.response_header keywords. | Fedora, Suricata | 8.1 | ||
2024-02-26 | CVE-2024-24568 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.3, the rules inspecting HTTP2 headers can get bypassed by crafted traffic. The vulnerability has been patched in 7.0.3. | Fedora, Suricata | 5.3 | ||
2024-05-07 | CVE-2024-32663 | Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.5 and 6.0.19, a small amount of HTTP/2 traffic can lead to Suricata using a large amount of memory. The issue has been addressed in Suricata 7.0.5 and 6.0.19. Workarounds include disabling the HTTP/2 parser and reducing `app-layer.protocols.http2.max-table-size` value (default is 65536). | Suricata | 7.5 |
