A flaw was found in MuPDF. A remote attacker could exploit an integer overflow vulnerability by providing a maliciously crafted PDF file. This overflow occurs within the `pdf_load_image_imp` function, leading to a heap out-of-bounds write. This vulnerability can be exploited to achieve arbitrary code execution, allowing the attacker to run unauthorized commands on the affected system.

Description OSIDB Bzimport 2026-03-31 14:02:14 UTC 
An integer overflow vulnerability in 'pdf-image.c' in Artifex's MuPDF version 1.27.0 allows an attacker to maliciously craft a PDF that can trigger an integer overflow within the 'pdf_load_image_imp' function. This allows a heap out-of-bounds write that could be exploited for arbitrary code execution.
