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.
