{"id":"GHSA-7945-5mcv-f2pp","summary":"LibOSDP vulnerable to a null pointer deref in osdp_reply_name","details":"### Issue:\nAt ospd_common.c, on the osdp_reply_name function, any reply id between REPLY_ACK and REPLY_XRD is valid, but names array do not declare all of the range. On a case of an undefined reply id within the range, name will be null (`name = names[reply_id - REPLY_ACK];`). Null name will casue a crash on next line: `if (name[0] == '\\0')` as null[0] is invalid.\n\n### Attack:\nAs this logic is not limited to a secure connection, attacker may trigger this vulnerability without any prior knowledge.\n\n### Impact\nDenial of Service\n\n### Patch\nThe issue has been patched in 24409e98a260176765956ec766a04cb35984fab1\n","aliases":["CVE-2024-52296","PYSEC-2026-1534"],"modified":"2026-07-07T17:56:41.141854292Z","published":"2024-03-08T17:33:46Z","database_specific":{"cwe_ids":["CWE-476"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-03-08T17:33:46Z","nvd_published_at":"2024-11-12T16:15:26Z"},"references":[{"type":"WEB","url":"https://github.com/goToMain/libosdp/security/advisories/GHSA-7945-5mcv-f2pp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-52296"},{"type":"WEB","url":"https://github.com/goToMain/libosdp/commit/24409e98a260176765956ec766a04cb35984fab1"},{"type":"PACKAGE","url":"https://github.com/goToMain/libosdp"}],"affected":[{"package":{"name":"libosdp","ecosystem":"PyPI","purl":"pkg:pypi/libosdp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/03/GHSA-7945-5mcv-f2pp/GHSA-7945-5mcv-f2pp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
