MITRE ATT&CK
1 technique across 1 tactic: Impact The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | Typically causes application crash (denial of service). In some cases, may be exploitable for code execution on systems without memory protection. With a CVSS score of 7.5 (HIGH), this represents a significant risk. |
| Exploit ScenarioDerived | An attacker provides input that causes a code path where a pointer is dereferenced without a prior NULL check, crashing the application. |

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Version 8.0.0's usage of the tls.subjectaltname keyword can lead to a segmentation fault when the decoded subjectaltname contains a NULL byte. This issue is fixed in version 8.0.1. To workaround this issue, disable rules using the tls.subjectaltname keyword.

RemediationAI
A vendor patch is available — apply it immediately. Add NULL checks before pointer dereference operations. Use static analysis to identify potential NULL pointer issues. Enable compiler warnings.

Attack Technique
A null pointer dereference occurs when a program attempts to access memory through a pointer that has been set to NULL (address 0x0).
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
