{"id":"PYSEC-2026-1534","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","GHSA-7945-5mcv-f2pp"],"modified":"2026-07-07T17:46:51.294684250Z","published":"2026-07-07T11:45:34.729113Z","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"},{"type":"PACKAGE","url":"https://pypi.org/project/libosdp"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-7945-5mcv-f2pp"}],"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/pypa/advisory-database/blob/main/vulns/libosdp/PYSEC-2026-1534.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
