Ghostscript for Windows is vulnerable to local privilege escalation through PostScript resource file hijacking. Due to the application searching for PostScript resource files in predictable paths under C:\\gs\\ that do not exist by default on Windows installations, combined with Windows default ACLs allowing any authenticated user to create directories at the root of C:\\, an attacker who is an authenticated local user can create the expected directory structure and plant a malicious PostScript file. When any user or service subsequently runs Ghostscript, the planted file is automatically loaded and executed with the full privileges of the Ghostscript process. This results in full compromise of Ghostscript process context, as well as running arbitrary code on the machine with Ghostscript process privileges. This issue was fixed in version 10.08.0.

MuPDF before 1.27 contains an ANSI injection vulnerability in mutool that allows attackers to inject arbitrary ANSI escape sequences through crafted PDF metadata fields. Attackers can embed malicious ANSI escape codes in PDF metadata that are passed unsanitized to terminal output when running mutool info, enabling them to manipulate terminal display for social engineering attacks such as presenting fake prompts or spoofed commands.

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.

A path traversal and arbitrary file write vulnerability exist in the embedded get function in '_main_.py' in PyMuPDF version, 1.26.5.
