CVE-2011-0257
HighSummary
Błąd związany z podpisem liczby całkowitej w Apple QuickTime przed wersją 7.7 umożliwia zdalnym atakującym wykonanie dowolnego kodu lub spowodowanie awarii aplikacji poprzez spreparowany opcode PnSize w pliku PICT, co prowadzi do przepełnienia bufora na stosie.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z QuickTime. Dodatkowo, może powodować awarie aplikacji, co wpływa na dostępność usług.
Recommendation
Zaleca się aktualizację Apple QuickTime do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować i ograniczać otwieranie plików PICT z nieznanych źródeł.
