A remote attacker can supply JavaScript input that triggers an exception and reaches jslPrintTokenLineMarker(), which passes the address of a 4-byte int column variable to jsvGetLineAndCol() as a size_t pointer. jsvGetLineAndCol() performs an 8-byte write through the mismatched pointer, overwriting adjacent stack memory." } ], "affected": [ { "vendor": "n/a", "product": "n/a", "versions": [ { "version": "n/a", "status": "affected" } ] } ], "references": [ { "url": "https://github.com/espruino/Espruino/commit/ecd7d43e084ba9aafa8245609347fe0f4383b38c" } ], "problemTypes": [ { "descriptions": [ { "type": "text", "lang": "en", "description": "n/a" } ] } ] } }, "dataVersion": "5.2" }
