Arch Linux Security Advisory ASA-201807-3
=========================================
Severity: Critical
Date : 2018-07-11
CVE-ID : CVE-2018-10895
Package : qutebrowser
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-735
Summary
=======
The package qutebrowser before version 1.4.1-1 is vulnerable to
arbitrary code execution.
Resolution
==========
Upgrade to 1.4.1-1.
# pacman -Syu "qutebrowser>=1.4.1-1"
The problem has been fixed upstream in version 1.4.1.
Workaround
==========
It's possible to patch out the vulnerable code via a config.py file
from qutebrowser.browser import qutescheme
qutescheme._qute_settings_set = lambda url: ('text/html', '')
Description
===========
Due to a CSRF vulnerability affecting the qute://settings page, it was
possible for websites to modify qutebrowser settings. Via settings like
editor.command, this possibly allowed websites to execute arbitrary
code.
Impact
======
A remote attacker is able to execute code with a specially crafted web
page.
