CVE-2012-2088
HighSummary
Błąd związany z podpisem liczby całkowitej w funkcji TIFFReadDirectory w libtiff 3.9.4 i wcześniejszych wersjach umożliwia zdalnym atakującym spowodowanie awarii aplikacji oraz potencjalne wykonanie dowolnego kodu poprzez negatywną głębokość kafelka w obrazie TIFF. To prowadzi do nieprawidłowej konwersji między typami ze znakiem a bez znaku, co skutkuje przepełnieniem bufora w stercie.
Risk Assessment
Organizacja może być narażona na ataki, które prowadzą do awarii aplikacji oraz potencjalnego zdalnego wykonania kodu, co może skutkować utratą danych lub przejęciem kontroli nad systemem.
Recommendation
Zaleca się aktualizację biblioteki libtiff do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów pod kątem nieautoryzowanych działań.

Original NVD description (English source)
Integer signedness error in the TIFFReadDirectory function in tif_dirread.c in libtiff 3.9.4 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a negative tile depth in a tiff image, which triggers an improper conversion between signed and unsigned types, leading to a heap-based buffer overflow.
