Arch Linux Security Advisory ASA-201711-3
=========================================

Severity: High
Date    : 2017-11-01
CVE-ID  : CVE-2017-14685 CVE-2017-14686 CVE-2017-14687 CVE-2017-15587
Package : mupdf-tools
Type    : arbitrary code execution
Remote  : No
Link    : https://security.archlinux.org/AVG-458

Summary
=======

The package mupdf-tools before version 1.11-5 is vulnerable to
arbitrary code execution.

Resolution
==========

Upgrade to 1.11-5.

# pacman -Syu "mupdf-tools>=1.11-5"

The problems have been fixed upstream but no release is available yet.

Workaround
==========

None.

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

- CVE-2017-14685 (arbitrary code execution)

Artifex MuPDF 1.11 allows attackers to cause a denial of service or
possibly have unspecified other impact via a crafted .xps file. This
occurs because xps_load_links_in_glyphs in xps/xps-link.c does not
verify that an xps font could be loaded.

- CVE-2017-14686 (arbitrary code execution)

Artifex MuPDF 1.11 allows attackers to execute arbitrary code or cause
a denial of service via a crafted .xps file. This occurs because
read_zip_dir_imp in fitz/unzip.c does not check whether size fields in
a ZIP entry are negative numbers.

- CVE-2017-14687 (arbitrary code execution)

Artifex MuPDF 1.11 allows attackers to cause a denial of service or
possibly have unspecified other impact via a crafted .xps file. This
occurs because of mishandling of XML tag name comparisons.

- CVE-2017-15587 (arbitrary code execution)

An integer overflow leading to an out-of-bounds wrte has been found in
mupdf <= 1.11. The parsing of a crafted PDF might allow an attacker to
write controlled data to an arbitrary location in memory when
performing truncated xref checks.

Impact
======

An attacker is able to execute arbitrary code on the affected host by
providing a maliciously-crafted .xps or .pdf file.
