Summary
Substance3D - wersje Stager 3.1.6 i wcześniejsze są podatne na lukę typu out-of-bounds przy analizowaniu spreparowanego pliku, co może prowadzić do odczytu poza końcem przydzielonej struktury pamięci. Atakujący może wykorzystać tę podatność do wykonania kodu w kontekście bieżącego użytkownika.
Risk Assessment
Wykorzystanie tej luki wymaga interakcji użytkownika, ponieważ ofiara musi otworzyć złośliwy plik. Może to prowadzić do nieautoryzowanego dostępu do systemu i potencjalnych szkód dla organizacji.
Recommendation
Zaleca się aktualizację Substance3D do wersji 3.1.7 lub nowszej oraz edukację użytkowników na temat ryzyk związanych z otwieraniem nieznanych plików.

Original NVD description (English source)
Substance3D - Stager versions 3.1.6 and earlier are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
