Sdl

An exploitable integer overflow vulnerability exists when creating a new RGB Surface in SDL 2.0.5. A specially crafted file can cause an integer overflow resulting in too little memory being allocated which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.

An exploitable buffer overflow vulnerability exists in the XCF property handling functionality of SDL_image 2.0.1. A specially crafted xcf file can cause a stack-based buffer overflow resulting in potential code execution. An attacker can provide a specially crafted XCF file to trigger this vulnerability.

SDL_image is a library to load images of various formats as SDL surfaces. In do_layer_surface() in src/IMG_xcf.c, pixel index values from decoded XCF tile data are used directly as colormap indices without validating them against the colormap size (cm_num). A crafted .xcf file with a small colormap and out-of-range pixel indices causes heap out-of-bounds reads of up to 762 bytes past the colormap allocation. Both IMAGE_INDEXED code paths are affected (bpp=1 and bpp=2). The leaked heap bytes are written into the output surface pixel data, making them potentially observable in the rendered image. This vulnerability is fixed with commit 996bf12888925932daace576e09c3053410896f8.

Buffer overflow in the LWZReadByte function in IMG_gif.c in SDL_image before 1.2.7 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted GIF file, a similar issue to CVE-2006-4484. NOTE: some of these details are obtained from third party information.

Heap-based buffer overflow in the IMG_LoadLBM_RW function in IMG_lbm.c in SDL_image before 1.2.7 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted IFF ILBM file. NOTE: some of these details are obtained from third party information.
