| CVE-2025-64334 | 1 Oisf | 1 Suricata | 2025-12-05 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, compressed HTTP data can lead to unbounded memory growth during decompression. This issue has been patched in version 8.0.2. A workaround involves disabling LZMA decompression or limiting response-body-limit size. | ||||
| CVE-2025-64333 | 1 Oisf | 1 Suricata | 2025-12-05 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a large HTTP content type, when logged can cause a stack overflow crashing Suricata. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves limiting stream.reassembly.depth to less then half the stack size. Increasing the process stack size makes it less likely the bug will trigger. | ||||
| CVE-2025-64332 | 1 Oisf | 1 Suricata | 2025-12-05 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a stack overflow that causes Suricata to crash can occur if SWF decompression is enabled. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling SWF decompression (swf-decompression in suricata.yaml), it is disabled by default; set decompress-depth to lower than half your stack size if swf-decompression must be enabled. | ||||
| CVE-2025-64330 | 1 Oisf | 1 Suricata | 2025-12-05 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a single byte read heap overflow when logging the verdict in eve.alert and eve.drop records can lead to crashes. This requires the per packet alert queue to be filled with alerts and then followed by a pass rule. This issue has been patched in versions 7.0.13 and 8.0.2. To reduce the likelihood of this issue occurring, the alert queue size a should be increased (packet-alert-max in suricata.yaml) if verdict is enabled. | ||||
| CVE-2025-64344 | 1 Oisf | 1 Suricata | 2025-12-03 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size. | ||||
| CVE-2025-64331 | 1 Oisf | 1 Suricata | 2025-11-28 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a stack overflow can occur on large HTTP file transfers if the user has increased the HTTP response body limit and enabled the logging of printable http bodies. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves using default HTTP response body limits and/or disabling http-body-printable logging; body logging is disabled by default. | ||||
| CVE-2025-64335 | 1 Oisf | 1 Suricata | 2025-11-28 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data. | ||||
| CVE-2025-29918 | 1 Oisf | 1 Suricata | 2025-11-03 | 6.2 Medium |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine.

| CVE-2024-37151 | 1 Oisf | 1 Suricata | 2025-11-03 | 5.3 Medium |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Mishandling of multiple fragmented packets using the same IP ID value can lead to packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-packet, enable `defrag` to reduce the scope of the problem. | ||||
| CVE-2024-32663 | 1 Oisf | 1 Suricata | 2025-11-03 | 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-2023-35852 | 1 Oisf | 1 Suricata | 2025-11-03 | 7.5 High |
| In Suricata before 6.0.13 (when there is an adversary who controls an external source of rules), a dataset filename, that comes from a rule, may trigger absolute or relative directory traversal, and lead to write access to a local filesystem. This is addressed in 6.0.13 by requiring allow-absolute-filenames and allow-write (in the datasets rules configuration section) if an installation requires traversal/writing in this situation. | ||||
| CVE-2021-45098 | 2 Debian, Oisf | 2 Debian Linux, Suricata | 2025-11-03 | 7.5 High |
| An issue was discovered in Suricata before 6.0.4. It is possible to bypass/evade any HTTP-based signature by faking an RST TCP packet with random TCP options of the md5header from the client side. After the three-way handshake, it's possible to inject an RST ACK with a random TCP md5header option. Then, the client can send an HTTP GET request with a forbidden URL. The server will ignore the RST ACK and send the response HTTP packet for the client's request. These packets will not trigger a Suricata reject action. | ||||
| CVE-2024-45797 | 1 Oisf | 1 Libhtp | 2025-11-03 | 7.5 High |
| LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. Prior to version 0.5.49, unbounded processing of HTTP request and response headers can lead to excessive CPU time and memory utilization, possibly leading to extreme slowdowns. This issue is addressed in 0.5.49. | ||||
| CVE-2024-23837 | 2 Fedoraproject, Oisf | 2 Fedora, Libhtp | 2025-11-03 | 7.5 High |
| LibHTP is a security-aware parser for the HTTP protocol. Crafted traffic can cause excessive processing time of HTTP headers, leading to denial of service. This issue is addressed in 0.5.46. | ||||
| CVE-2025-59150 | 1 Oisf | 1 Suricata | 2025-10-23 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Version 8.0.0's usage of the tls.subjectaltname keyword can lead to a segmentation fault when the decoded subjectaltname contains a NULL byte. This issue is fixed in version 8.0.1. To workaround this issue, disable rules using the tls.subjectaltname keyword. | ||||
| CVE-2025-59149 | 1 Oisf | 1 Suricata | 2025-10-06 | 6.2 Medium |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In version 8.0.0, rules using keyword ldap.responses.attribute_type (which is long) with transforms can lead to a stack buffer overflow during Suricata startup or during a rule reload. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules with ldap.responses.attribute_type and transforms. | ||||
| CVE-2025-59148 | 1 Oisf | 1 Suricata | 2025-10-06 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 8.0.0 and below incorrectly handle the entropy keyword when not anchored to a "sticky" buffer, which can lead to a segmentation fault. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate they are anchored to a sticky buffer. | ||||
| CVE-2025-59147 | 1 Oisf | 1 Suricata | 2025-10-06 | 7.5 High |
| Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 7.0.11 and below, as well as 8.0.0, are vulnerable to detection bypass when crafted traffic sends multiple SYN packets with different sequence numbers within the same flow tuple, which can cause Suricata to fail to pick up the TCP session. In IDS mode this can lead to a detection and logging bypass. In IPS mode this will lead to the flow getting blocked. This issue is fixed in versions 7.0.12 and 8.0.1. | ||||
