datasets: ruleset declared settings can lead to resource starvation

Moderate
victorjulien published GHSA-27g3-pmvp-j9cv Apr 10, 2025

Package

suricata

Affected versions

<7.0.9

Patched versions

7.0.9

Description

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.

Impact

Untrusted rules can lead to large memory allocations, potentially leading to denial of service due to resource starvation.

Patches

Upgrade to 7.0.9.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
