The array offsets_to_Names is dynamically allocated on the stack using exp->NumberOfFunctions as its size. However, the loop uses exp->NumberOfNames to iterate over it and set its components value. Therefore, the loop code assumes that exp->NumberOfFunctions is greater than ordinal at each iteration. This can lead to arbitrary code execution."}], "lastModified": "2023-03-24T15:19:58.157", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:pev_project:pev:0.81:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "137049BB-7F2D-433A-8809-A4CE073CC14D"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
