CVE-2011-2690
HighSummary
Przepełnienie bufora w libpng w wersjach 1.0.x przed 1.0.55, 1.2.x przed 1.2.45, 1.4.x przed 1.4.8 oraz 1.5.x przed 1.5.4, występuje, gdy aplikacja wywołuje funkcję png_rgb_to_gray, ale nie używa funkcji png_set_expand. Umożliwia to zdalnym atakującym nadpisanie pamięci dowolną ilością danych za pomocą spreparowanego obrazu PNG.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego wykonania kodu lub destabilizacji aplikacji, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację libpng do najnowszej wersji, aby usunąć tę podatność oraz przeglądanie aplikacji korzystających z tej biblioteki w celu zapewnienia odpowiednich zabezpieczeń.

- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
