| CVE-2025-29918 | 1 Oisf | 1 Suricata | 2025-05-29 | 6.2 Medium |
| 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. | ||||
| CVE-2025-29917 | 1 Oisf | 1 Suricata | 2025-05-29 | 6.2 Medium |
| 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. | ||||
| CVE-2025-29916 | 1 Oisf | 1 Suricata | 2025-05-29 | 6.2 Medium |
| 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. | ||||
| CVE-2025-29915 | 1 Oisf | 1 Suricata | 2025-05-29 | 7.5 High |
| 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. | ||||
| CVE-2024-28870 | 1 Oisf | 1 Suricata | 2025-04-28 | 7.5 High |
| 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. | ||||
| CVE-2013-5919 | 2 Oisf, Openinfosecfoundation | 2 Suricata, Suricata | 2025-04-12 | N/A |
| Suricata before 1.4.6 allows remote attackers to cause a denial of service (crash) via a malformed SSL record. | ||||
| CVE-2024-55605 | 1 Oisf | 1 Suricata | 2025-03-31 | 7.5 High |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a large input buffer to the to_lowercase, to_uppercase, strip_whitespace, compress_whitespace, dotprefix, header_lowercase, strip_pseudo_headers, url_decode, or xor transform can lead to a stack overflow causing Suricata to crash. The issue has been addressed in Suricata 7.0.8. | ||||
| CVE-2024-55626 | 1 Oisf | 1 Suricata | 2025-03-31 | 3.3 Low |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a large BPF filter file provided to Suricata at startup can lead to a buffer overflow at Suricata startup. The issue has been addressed in Suricata 7.0.8. | ||||
| CVE-2024-55627 | 1 Oisf | 1 Suricata | 2025-03-31 | 5.9 Medium |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue has been addressed in Suricata 7.0.8. | ||||
| CVE-2024-55628 | 1 Oisf | 1 Suricata | 2025-03-31 | 7.5 High |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages containing very large hostnames which can be costly to decode, and lead to very large DNS log records. While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8. | ||||
| CVE-2024-55629 | 1 Oisf | 1 Suricata | 2025-03-31 | 7.5 High |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, TCP streams with TCP urgent data (out of band data) can lead to Suricata analyzing data differently than the applications at the TCP endpoints, leading to possible evasions. Suricata 7.0.8 includes options to allow users to configure how to handle TCP urgent data. In IPS mode, you can use a rule such as drop tcp any any -> any any (sid:1; tcp.flags:U*;) to drop all the packets with urgent flag set. | ||||
| CVE-2024-24568 | 2 Fedoraproject, Oisf | 2 Fedora, Suricata | 2025-02-13 | 5.3 Medium |
| 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. | ||||
| CVE-2024-23839 | 2 Fedoraproject, Oisf | 2 Fedora, Suricata | 2025-02-13 | 7.1 High |
| 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. | ||||
| CVE-2024-23836 | 2 Fedoraproject, Oisf | 2 Fedora, Suricata | 2025-02-13 | 7.5 High |
| 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 `stream.reassembly.depth` value helps reduce the severity of the issue. | ||||
| CVE-2024-23835 | 2 Fedoraproject, Oisf | 2 Fedora, Suricata | 2025-02-13 | 7.5 High |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.3, excessive memory use during pgsql parsing could lead to OOM-related crashes. This vulnerability is patched in 7.0.3. As workaround, users can disable the pgsql app layer parser. | ||||
| CVE-2020-19678 | 2 Oisf, Pfsense | 3 Suricata, Pfsense, Suricata Package | 2025-02-12 | 7.5 High |
| 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. | ||||
| CVE-2024-32867 | 1 Oisf | 1 Suricata | 2024-12-19 | 5.3 Medium |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.5 and 6.0.19, various problems in handling of fragmentation anomalies can lead to mis-detection of rules and policy. This vulnerability is fixed in 7.0.5 or 6.0.19. | ||||
| CVE-2024-32664 | 1 Oisf | 1 Suricata | 2024-12-19 | 5.3 Medium |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.5 and 6.0.19, specially crafted traffic or datasets can cause a limited buffer overflow. This vulnerability is fixed in 7.0.5 and 6.0.19. Workarounds include not use rules with `base64_decode` keyword with `bytes` option with value 1, 2 or 5 and for 7.0.x, setting `app-layer.protocols.smtp.mime.body-md5` to false. | ||||
| CVE-2024-32663 | 1 Oisf | 1 Suricata | 2024-12-19 | 7.5 High |
| 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). | ||||
| CVE-2023-35853 | 1 Oisf | 1 Suricata | 2024-12-11 | 9.8 Critical |
| In Suricata before 6.0.13, an adversary who controls an external source of Lua rules may be able to execute Lua code. This is addressed in 6.0.13 by disabling Lua unless allow-rules is true in the security lua configuration section. | ||||
