{"id":"CVE-2023-25565","summary":"GSS-NTLMSSP vulnerable to incorrect free when decoding target information","details":"GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the `cb` and `sh` buffers contain a copy of the data that needs to be freed. However, that is not the case. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point. This will likely trigger an assertion failure in `free`, causing a denial-of-service. This issue is fixed in version 1.2.0.","aliases":["GHSA-7q7f-wqcg-mvfg"],"modified":"2026-05-15T04:06:30.748620257Z","published":"2023-02-14T17:35:41.222Z","related":["ALSA-2023:3097","openSUSE-SU-2023:0048-1","openSUSE-SU-2024:12701-1"],"database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25565.json","cwe_ids":["CWE-590"]},"references":[{"type":"WEB","url":"https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25565.json"},{"type":"ADVISORY","url":"https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-7q7f-wqcg-mvfg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25565"},{"type":"FIX","url":"https://github.com/gssapi/gss-ntlmssp/commit/c16100f60907a2de92bcb676f303b81facee0f64"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
