FastStone Image Viewer v.<= 7.5 is affected by a Stack-based Buffer Overflow at
0x005BDF49, affecting the CUR file parsing functionality (
BITMAPINFOHEADER Structure, ‘
BitCount‘ file format field), that will end up corrupting the Structure Exception Handler (SEH). Attackers could exploit this issue to achieve code execution when a user opens or views a malformed/specially crafted CUR file.
