ImageMagick MAT Decoder Heap Over-Read (before 7.1.2-16 / 6.9.13-41)
CVE-2026-28692 Published on March 9, 2026

ImageMagick has a heap buffer over-read via 32-bit integer overflow in MAT decoder
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, MAT decoder uses 32-bit arithmetic due to incorrect parenthesization resulting in a heap over-read. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Weakness Type

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.
