Doc Text:
A flaw was found in ImageMagick. A remote attacker can exploit this vulnerability to achieve arbitrary code execution or trigger an application crash, resulting in a denial of service (DoS). By providing a specially crafted PICT image file with manipulated dimension values, an integer overflow occurs during memory address calculations on 32-bit systems, allowing data to be written outside the allocated heap memory buffer.

Description OSIDB Bzimport 2026-10-13 14:18:47 UTC 
ImageMagick before 7.1.2-33 and 6.9.13-58 contains a heap buffer underwrite vulnerability in DecodeImage() in coders/pict.c on 32-bit builds due to pointer arithmetic overflow. Attackers can supply a crafted PICT file with maximized row, column and bytes-per-line values to bypass bounds checks and write up to 128 controlled bytes below the heap buffer, causing crashes or code execution.
