Prior to version 1.2.0, memory corruption can be triggered when decoding UTF16 strings. The variable `outlen` was not initialized and could cause writing a zero to an arbitrary place in memory if `ntlm_str_convert()` were to fail, which would leave `outlen` uninitialized. This can lead to a denial of service if the write hits unmapped memory or randomly corrupts a byte in the application memory space. This vulnerability can trigger an out-of-bounds write, leading to memory corruption. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point. This issue is fixed in version 1.2.0."}], "source": {"advisory": "GHSA-r85x-q5px-9xfq", "discovery": "UNKNOWN"}}, "adp": [{"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T11:25:19.239Z"}, "title": "CVE Program Container", "references": [{"name": "https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-r85x-q5px-9xfq", "tags": ["x_refsource_CONFIRM", "x_transferred"], "url": "https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-r85x-q5px-9xfq"}, {"name": "https://github.com/gssapi/gss-ntlmssp/commit/c753000eb31835c0664e528fbc99378ae0cbe950", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/gssapi/gss-ntlmssp/commit/c753000eb31835c0664e528fbc99378ae0cbe950"}, {"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": "2025-03-10T20:57:39.173930Z", "id": "CVE-2023-25564", "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": "2025-03-10T21:12:01.901Z"}}]}}
