In short
A specially crafted TCP stream can cause Suricata to crash due to a buffer overflow triggered by an integer underflow. This crash disrupts network security monitoring and intrusion detection capabilities.
Technical detail
An unsigned integer underflow in StreamingBufferSlideToOffsetWithRegions allows an attacker to craft a malicious TCP stream that causes a large memset operation to write beyond buffer boundaries. The vulnerability requires network access to send crafted packets; successful exploitation results in denial of service through segmentation fault, disabling intrusion detection/prevention functionality.
Summary generated and translated by AI from the official description.
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue has been addressed in Suricata 7.0.8.
