{"id":"CVE-2021-45423","details":"A Buffer Overflow vulnerabilityexists in Pev 0.81 via the pe_exports function from exports.c.. The array offsets_to_Names is dynamically allocated on the stack using exp-\u003eNumberOfFunctions as its size. However, the loop uses exp-\u003eNumberOfNames to iterate over it and set its components value. Therefore, the loop code assumes that exp-\u003eNumberOfFunctions is greater than ordinal at each iteration. This can lead to arbitrary code execution.","modified":"2026-03-14T11:17:10.774418Z","published":"2023-03-13T18:15:12.553Z","references":[{"type":"EVIDENCE","url":"https://github.com/merces/libpe/issues/35"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"0.81"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-45423.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
