ASA-201801-27: mupdf: arbitrary code execution
Arch Linux Security Advisory ASA-201801-27
==========================================

Severity: High
Date : 2018-01-30
CVE-ID : CVE-2017-17858
Package : mupdf
Type : arbitrary code execution
Remote : No
Link : https://security.archlinux.org/AVG-599

Summary
=======

The package mupdf before version 1.12.0-2 is vulnerable to arbitrary
code execution.

Resolution
==========

Upgrade to 1.12.0-2.

# pacman -Syu "mupdf>=1.12.0-2"

The problem has been fixed upstream but no release is available yet.

Workaround
==========

None.

Description
===========

Heap-based buffer overflow in the ensure_solid_xref function in
pdf/pdf-xref.c in Artifex MuPDF 1.12.0 allows an attacker to
potentially execute arbitrary code via a crafted PDF file, because xref
subsection object numbers are unrestricted.

Impact
======

An attacker is able to execute arbitrary code on the affected host by
tricking the user to open or process a maliciously crafted PDF
document.
