CVE-2017-3730 (GCVE-0-2017-3730)

Vulnerability from cvelistv5 – Published: 2017-05-04 19:00 – Updated: 2024-09-16 17:48

Title

Bad (EC)DHE parameters cause a client crash

Summary

In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack.

Severity

No CVSS data available.

CWE

NULL pointer deference

Assigner

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
