CVE-ID : CVE-2017-17858
Package : mupdf-tools
Type : arbitrary code execution
Remote : No
Link : https://security.archlinux.org/AVG-599
Summary
=======
The package mupdf-tools before version 1.12.0-2 is vulnerable to
arbitrary code execution.
Resolution
==========
Upgrade to 1.12.0-2.
# pacman -Syu "mupdf-tools>=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.
