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.\n\n"}],"source":{"advisory":"GHSA-mfm4-6g58-jw74","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T11:25:19.220Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-mfm4-6g58-jw74","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-mfm4-6g58-jw74"},{"name":"https://github.com/gssapi/gss-ntlmssp/commit/8660fb16474054e692a596e9c79670cd4d3954f4","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/commit/8660fb16474054e692a596e9c79670cd4d3954f4"},{"name":"https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-03-10T20:58:44.101141Z","id":"CVE-2023-25566","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-10T21:11:49.420Z"}}]}}
