Summary

[none]

Details

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 'pdfloadimage_imp' function. This allows a heap out-of-bounds write that could be exploited for arbitrary code execution.
