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 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.

Executive Summary

This vulnerability is a stack overflow in Suricata, a network IDS, IPS, and NSM engine. It occurs during large HTTP file transfers if the user has increased the HTTP response body limit and enabled logging of printable HTTP bodies. This can cause the software to overflow its stack, potentially leading to crashes or other unintended behavior. The issue has been fixed in versions 7.0.13 and 8.0.2.

Impact Analysis

The vulnerability can cause Suricata to experience a stack overflow during large HTTP file transfers under certain configurations, which may lead to denial of service by crashing the application or disrupting network monitoring and intrusion detection capabilities. This can reduce the effectiveness of network security monitoring and potentially allow malicious traffic to go undetected.

Mitigation Strategies

To mitigate this vulnerability, immediately upgrade Suricata to version 7.0.13 or 8.0.2 or later. Alternatively, as a workaround, revert to the default HTTP response body limits and/or disable the logging of printable HTTP bodies, since body logging is disabled by default.
