W infrastrukturze ci\u0105g\u0142ego testowania fuzzingowego OSS-Fuzz dodano mo\u017cliwo\u015b\u0107 testowania projekt\u00f3w napisanych w j\u0119zyku Lua, obok wcze\u015bniej wspieranych j\u0119zyk\u00f3w C\/C++, Go, Swift, Rust, Python, JavaScript i Java. Integracja zosta\u0142a zrealizowana dzi\u0119ki projektowi luzer, kt\u00f3ry rozwija specjalistyczne narz\u0119dzia do testowania fuzzingowego kodu w j\u0119zyku Lua oraz rozszerze\u0144 do Lua, napisanych w C\/C++. <\/p>\n

Projekt wykorzystuje bibliotek\u0119 libFuzzer i mo\u017ce by\u0107 u\u017cywany razem z narz\u0119dziami AddressSanitizer, MemorySanitizer, LeakSanitizer, ThreadSanitizer i Undefined Behavior Sanitizer, kt\u00f3re na podstawie wykrytych podczas testowania fuzzingowego problem\u00f3w, pozwalaj\u0105 okre\u015bli\u0107 obecno\u015b\u0107 typowych luk bezpiecze\u0144stwa spowodowanych przepe\u0142nieniem bufora, przepe\u0142nieniem liczb ca\u0142kowitych, odwo\u0142aniami do nieinicjowanych i zwolnionych obszar\u00f3w, wyciekami pami\u0119ci, dereferencj\u0105 wska\u017anik\u00f3w i problemami z blokowaniem. Kod projektu jest dost\u0119pny na licencji ISC. <\/p>\n

Podczas pracy luzer przeszukuje mo\u017cliwe kombinacje danych wej\u015bciowych i generuje raport o wszystkich wykrytych awariach i nieprzechwyconych wyj\u0105tkach. Na przyk\u0142ad, podczas testowania w luzer biblioteki analizuj\u0105cej format MsgPack antirez\/lua-cmsgpack wykazano, \u017ce dane z du\u017c\u0105 liczb\u0105 tablic mog\u0105 prowadzi\u0107 do przepe\u0142nienia stosu. <\/p>\n

W ramach projektu lunapark narz\u0119dzie luzer jest stosowane do testowania PUC Rio Lua, kompilatora \u015bledz\u0105cego LuaJIT, wysokowydajnej bazy danych oraz serwera<\/a> aplikacji Tarantool, a tak\u017ce do testowania zewn\u0119trznych modu\u0142\u00f3w Lua. <\/p>\n

Deweloperzy otwartych projekt\u00f3w mog\u0105 doda\u0107 swoje repozytoria do testowania, przygotowuj\u0105c szablon testowania fuzzingowego i wysy\u0142aj\u0105c specjalny wniosek przez pull request. W przypadku wykrycia b\u0142\u0119d\u00f3w deweloperzy automatycznie otrzymuj\u0105 powiadomienie, a prywatny wniosek o napraw\u0119 jest tworzony (aby unikn\u0105\u0107 przedwczesnego wycieku informacji o lukach, zg\u0142oszenie jest tworzone w systemie \u015bledzenia b\u0142\u0119d\u00f3w z ograniczonym dost\u0119pem). OSS Fuzz \u015bledzi status naprawy b\u0142\u0119du i automatycznie zamyka zg\u0142oszenie, je\u015bli przestaje si\u0119 powtarza\u0107. Informacje o problemie staj\u0105 si\u0119 publicznie dost\u0119pne po 7 dniach od naprawy lub po 90 dniach od momentu wykrycia b\u0142\u0119du, je\u015bli problem pozostaje nienaprawiony.
