CVE-2012-2386
HighSummary
Przepełnienie całkowite w funkcji phar_parse_tarfile w rozszerzeniu phar w PHP przed wersją 5.3.14 oraz 5.4.x przed wersją 5.4.4 umożliwia zdalnym atakującym spowodowanie awarii aplikacji lub potencjalne wykonanie dowolnego kodu poprzez spreparowany plik tar, który wywołuje przepełnienie bufora w pamięci heap.
Risk Assessment
Podatność ta może prowadzić do awarii aplikacji, co wpływa na dostępność usług. Istnieje również ryzyko wykonania dowolnego kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa.
Recommendation
Zaleca się aktualizację PHP do wersji 5.3.14 lub 5.4.4 i nowszych, aby usunąć tę podatność. Dodatkowo, należy monitorować i weryfikować pliki tar przesyłane do aplikacji.

Original NVD description (English source)
Integer overflow in the phar_parse_tarfile function in tar.c in the phar extension in PHP before 5.3.14 and 5.4.x before 5.4.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted tar file that triggers a heap-based buffer overflow.
