Prior to version 1.2.0, a memory leak can be triggered when parsing usernames which can trigger a denial-of-service. The domain portion of a username may be overridden causing an allocated memory area the size of the domain name to be leaked. An attacker can leak memory via the main `gss_accept_sec_context` entry point, potentially causing a denial-of-service. This issue is fixed in version 1.2.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-401"],"references":["https://github.com/gssapi/gss-ntlmssp/commit/8660fb16474054e692a596e9c79670cd4d3954f4","https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0","https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-mfm4-6g58-jw74","https://github.com/gssapi/gss-ntlmssp/commit/8660fb16474054e692a596e9c79670cd4d3954f4","https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0"],"products":["gss-ntlmssp_project:gss-ntlmssp"],"source":"nvd","synced_at":"2026-10-19T21:37:38.595364862+00:00"},"epss":{"cve":"CVE-2023-25566","score":0.01103,"percentile":0.6574,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
