CVE-2012-4433
HighSummary
W bibliotece GEGL (Generic Graphics Library) w wersji 0.2.0 występuje wiele przepełnień całkowitych w pliku operations/external/ppm-load.c. Atakujący zdalnie mogą spowodować awarię aplikacji lub potencjalnie wykonać dowolny kod, wykorzystując dużą wartość szerokości lub wysokości w obrazie Portable Pixel Map (ppm), co prowadzi do przepełnienia bufora w stercie.
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 biblioteki GEGL do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować i ograniczać wprowadzanie obrazów ppm z niezaufanych źródeł.

Original NVD description (English source)
Multiple integer overflows in operations/external/ppm-load.c in GEGL (Generic Graphics Library) 0.2.0 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a large (1) width or (2) height value in a Portable Pixel Map (ppm) image, which triggers a heap-based buffer overflow.
