Description
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to both 6.9.13-52 and 7.1.2-27, processing an extremely large JNX file on 32-bit platforms can cause an integer overflow, leading to a heap buffer over-write. This issue has been fixed in versions 6.9.13-52 and 7.1.2-27.

CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |
