Secunia Research has discovered two vulnerabilities in SWFTools, which can be exploited by malicious people to compromise a user's system. An integer overflow error within the "getPNG()" function in lib/png.c can be exploited to cause a heap-based buffer overflow via specially crafted PNG images. An integer overflow error within the "jpeg_load()" function in lib/jpeg.c can be exploited to cause a heap-based buffer overflow via specially crafted JPEG images.
