Title
Suricata DCERPC: unbounded fragment buffering leads to memory exhaustion
Summary
Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, crafted DCERPC traffic can cause Suricata to expand a buffer w/o limits, leading to memory exhaustion and the process getting killed. While reported for DCERPC over UDP, it is believed that DCERPC over TCP and SMB are also vulnerable. DCERPC/TCP in the default configuration should not be vulnerable as the default stream depth is limited to 1MiB. Versions 8.0.3 and 7.0.14 contain a patch. Some workarounds are available. For DCERPC/UDP, disable the parser. For DCERPC/TCP, the `stream.reassembly.depth` setting will limit the amount of data that can be buffered. For DCERPC/SMB, the `stream.reassembly.depth` can be used as well, but is set to unlimited by default. Imposing a limit here may lead to loss of visibility in SMB.

Title
Suricata dnp3: unbounded transaction growth
Summary
Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, specially crafted traffic can cause Suricata to consume large amounts of memory while parsing DNP3 traffic. This can lead to the process slowing down and running out of memory, potentially leading to it getting killed by the OOM killer. Versions 8.0.3 or 7.0.14 contain a patch. As a workaround, disable the DNP3 parser in the suricata yaml (disabled by default).

Suricata eve/alert: http1 xff handling can lead to denial of service
Summary
Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, various inefficiencies in xff handling, especially for alerts not triggered in a tx, can lead to severe slowdowns. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, disable XFF support in the eve configuration. The setting is disabled by default.

Title
Suricata datasets: stack overflow when saving a set
Summary
Suricata is a network IDS, IPS and NSM engine. While saving a dataset a stack buffer is used to prepare the data. Prior to versions 8.0.3 and 7.0.14, if the data in the dataset is too large, this can result in a stack overflow. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not use rules with datasets `save` nor `state` options.

Title
Suricata detect/alert: heap-use-after-free on alert queue expansion
Summary
Suricata is a network IDS, IPS and NSM engine. Prior to version 8.0.3 and 7.0.14, an unsigned integer overflow can lead to a heap use-after-free condition when generating excessive amounts of alerts for a single packet. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not run untrusted rulesets or run with less than 65536 signatures that can match on the same packet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
