ImageMagick 6.9.13-47/7.1.2-22 POF Over-Read in Poly Distortion
CVE-2026-45624 Published on June 10, 2026

ImageMagick: Heap Buffer Over-Read of a 4 bytes in distort operation.
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, when performing a polynomial distortion an out of bounds over-read of 24 bytes can occur when specifying specific arguments. This issue has been patched in versions 6.9.13-47 and 7.1.2-22.

Weakness Types

Out-of-bounds Read

The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.

What is an out-of-bounds array index Vulnerability?

The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array.

CVE-2026-45624 has been classified to as an out-of-bounds array index vulnerability or weakness.
