Affected: ImageMagick

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. In versions 7.1.2-9 and prior, the TIM (PSX TIM) image parser contains a critical integer overflow vulnerability in its ReadTIMImage function (coders/tim.c). The code reads width and height (16-bit values) from the file header and calculates image_size = 2 * width * height without checking for overflow. On 32-bit systems (or where size_t is 32-bit), this calculation can overflow if width and height are large (e.g., 65535), wrapping around to a small value. This results in a small heap allocation via AcquireQuantumMemory and later operations relying on the dimensions can trigger an out of bounds read. This issue is fixed in version 7.1.2-10.

Affected: NuGet: Magick.NET-Q16-AnyCPU, NuGet: Magick.NET-Q16-HDRI-AnyCPU, NuGet: Magick.NET-Q16-HDRI-x86, NuGet: Magick.NET-Q16-x86, NuGet: Magick.NET-Q8-AnyCPU, NuGet: Magick.NET-Q8-x86

### Summary The TIM (PSX TIM) image parser in ImageMagick contains a critical integer overflow vulnerability in the `ReadTIMImage` function (`coders/tim.c`). The code reads `width` and `height` (16-bit values) from the file header and calculates `image_size = 2 * width * height` without checking for overflow. On 32-bit systems (or where `size_t` is 32-bit), this calculation can overflow if `width` and `height` are large (e.g., 65535), wrapping around to a small value. This results in a small heap allocation via `AcquireQuantumMemory` and later operations relying on the dimensions can trigger an out of bounds read. ### Vulnerable Code File: `coders/tim.c` ```c width=ReadBlobLSBShort(image); height=ReadBlobLSBShort(image); image_size=2*width*height; // Line 234 - NO OVERFLOW CHECK! ```

### Impact This vulnerability can lead to Arbitrary Memory Disclosure due to an out of bounds read on 32-bit systems.
