Description

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.

Executive Summary

This vulnerability is a single byte read heap overflow in Suricata versions prior to 7.0.13 and 8.0.2. It occurs when logging the verdict in eve.alert and eve.drop records if the per packet alert queue is filled with alerts followed by a pass rule. This overflow can lead to crashes of the Suricata engine.

Impact Analysis

The vulnerability can cause Suricata to crash, potentially disrupting network intrusion detection and prevention operations. This could lead to loss of monitoring and protection capabilities, increasing the risk of undetected network attacks or intrusions.

Mitigation Strategies

Upgrade Suricata to version 7.0.13 or 8.0.2 or later where the vulnerability is patched. Additionally, increase the alert queue size by adjusting the 'packet-alert-max' setting in the suricata.yaml configuration file if verdict logging is enabled.
