Summary
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.
Risk Assessment
On 32-bit systems, this calculation can overflow, resulting in a small heap allocation and later out-of-bounds read. This may lead to data disclosure or application crash.
Recommendation
Update ImageMagick to version 7.1.2-10 or later. Avoid processing untrusted TIM files on 32-bit systems.

- CVE-2017-14682High
GetNextToken in MagickCore/token.c in ImageMagick 7.0.6 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted SVG document.
- CVE-2017-14137High
The ReadWEBPImage function in coders/webp.c in ImageMagick 7.0.6-5 has an issue with excessive memory allocation that depends only on a length field in a header.
- CVE-2017-13146High
In ImageMagick before version 6.9.8-5 and 7.x before version 7.0.5-6, there is a memory leak in the ReadMATImage function in coders/mat.c.
- CVE-2017-13143High
In ImageMagick before 6.9.7-6 and 7.x before 7.0.4-6, the ReadMATImage function in coders/mat.c uses uninitialized data, which might allow remote attackers to obtain sensitive information from process memory.
Original NVD description (English source)
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.
