The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant.
CVE-2011-5000 is a security vulnerability that . Impacting 1 product from openbsd organizations running these solutions should prioritize assessment and patching.
Documented in 2012, this vulnerability occurred amid the cloud computing expansion era, where traditional network perimeter security models were being reevaluated. Organizations were transitioning from isolated infrastructure to interconnected systems, creating new attack surfaces that vulnerabilities like this could exploit.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For openbsd's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
