CVE-2025-59148 Details
Description
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.
A vulnerability in Suricata versions 8.0.0 and earlier exists due to improper handling of the entropy keyword when not linked to a 'sticky' buffer. This mismanagement can cause a segmentation fault. The issue is present in the network IDS, IPS, and NSM engine developed by the Open Information Security Foundation (OISF) and the Suricata community.
Users can update to Suricata version 8.0.1, which addresses this vulnerability. Alternatively, users can disable rules that use the entropy keyword or ensure that those rules are anchored to a sticky buffer.
