CVE-2008-5286
HighSummary
Przepełnienie całkowite w funkcji _cupsImageReadPNG w CUPS od wersji 1.1.17 do 1.3.9 umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez obraz PNG z dużą wartością wysokości, co omija kontrolę walidacji i wywołuje przepełnienie bufora.
Risk Assessment
Atakujący może wykorzystać tę podatność do zdalnego wykonania kodu, co może prowadzić do przejęcia kontroli nad systemem lub wycieku danych. Organizacje powinny być świadome potencjalnych zagrożeń związanych z nieautoryzowanym dostępem do ich systemów.
Recommendation
Zaleca się aktualizację CUPS do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wprowadzić odpowiednie zabezpieczenia, takie jak filtrowanie lub skanowanie przesyłanych obrazów PNG.

Original NVD description (English source)
Integer overflow in the _cupsImageReadPNG function in CUPS 1.1.17 through 1.3.9 allows remote attackers to execute arbitrary code via a PNG image with a large height value, which bypasses a validation check and triggers a buffer overflow.
