CVE-2015-5334 (GCVE-0-2015-5334)

Vulnerability from cvelistv5 – Published: 2020-01-23 19:56 – Updated: 2024-08-06 06:41

Summary

Off-by-one error in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (program crash) or possible execute arbitrary code via a crafted X.509 certificate, which triggers a stack-based buffer overflow. Note: this vulnerability exists because of an incorrect fix for CVE-2014-3508.

Severity

No CVSS data available.
