CVE-2012-2841
HighSummary
W bibliotece libexif w wersji 0.6.20 występuje błąd przepełnienia bufora na stercie spowodowany niedoborem wartości całkowitej w funkcji exif_entry_get_value. Atakujący mogą wykorzystać ten błąd, przesyłając odpowiednio skonstruowany parametr rozmiaru bufora podczas formatowania tagu EXIF.
Risk Assessment
Podatność ta może umożliwić zdalnym atakującym wykonanie dowolnego kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z tej biblioteki. Może to prowadzić do przejęcia kontroli nad systemem lub wycieku danych.
Recommendation
Zaleca się aktualizację biblioteki libexif do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować systemy pod kątem nieautoryzowanych działań i potencjalnych exploitów.

Original NVD description (English source)
Integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 might allow remote attackers to execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
