Prior to version 1.2.0, multiple out-of-bounds reads when decoding NTLM fields can trigger a denial of service. A 32-bit integer overflow condition can lead to incorrect checks of consistency of length of internal buffers. Although most applications will error out before accepting a singe input buffer of 4GB in length this could theoretically happen. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point if the application allows tokens greater than 4GB in length. This can lead to a large, up to 65KB, out-of-bounds read which could cause a denial-of-service if it reads from unmapped memory. Version 1.2.0 contains a patch for the out-of-bounds reads."}], "source": {"advisory": "GHSA-jjjx-5qf7-9mgf", "discovery": "UNKNOWN"}}, "adp": [{"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T11:25:19.176Z"}, "title": "CVE Program Container", "references": [{"name": "https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-jjjx-5qf7-9mgf", "tags": ["x_refsource_CONFIRM", "x_transferred"], "url": "https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-jjjx-5qf7-9mgf"}, {"name": "https://github.com/gssapi/gss-ntlmssp/commit/97c62c6167299028d80765080e74d91dfc99efbd", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/gssapi/gss-ntlmssp/commit/97c62c6167299028d80765080e74d91dfc99efbd"}, {"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": "2025-03-10T20:57:41.972079Z", "id": "CVE-2023-25563", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"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": "2025-03-10T21:12:07.826Z"}}]}}
