Title: GD Graphics Library Remote Integer Overflow Vulnerability
Severity: CRITICAL
Description:
The GD Graphics Library (gdlib) is an open-source graphics library available for multiple platforms including Unix variants and Microsoft Windows. It is implemented in ANSI C and is designed to facilitate creation and manipulation of PNG, JPEG, and GIF image formats.
The gdlib library is affected by an integer overflow that facilitates a heap overflow. The library fails to do proper sanity checking on size values contained within image format files.
The problem presents itself when the library is used to process malicious image-format files. Specifically, the problem occurs in the 'gdImageCreateFromPngCtx()' function call in the 'gd_png.c' file. Two values are taken from the image file -- the pixel row and column value -- and multiplied together to allocate the memory required to store the compressed image. Once allocated, the image array is passed to the libPNG library where the image is first inflated using the zLib function 'inflate()' and then copied into heap memory in the 'png_combine_row()' function of the libPNG library.
An attacker may leverage this issue by providing an image with invalid row and column values, facilitating manipulation of process heap memory, potentially leading to code execution and compromise of the computer running the affected library.
Although gdlib version 2.0.28 is the only version reportedly affected by this issue, earlier versions are likely affected as well.
