Arch Linux Security Advisory ASA-201906-20
==========================================

Severity: High
Date    : 2019-06-25
CVE-ID  : CVE-2019-11708
Package : firefox
Type    : sandbox escape
Remote  : Yes
Link    : https://security.archlinux.org/AVG-997

Summary
=======

The package firefox before version 67.0.4-1 is vulnerable to sandbox
escape.

Resolution
==========

Upgrade to 67.0.4-1.

# pacman -Syu "firefox>=67.0.4-1"

The problem has been fixed upstream in version 67.0.4.

Workaround
==========

None.

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

An issue has been found in Firefox before 67.0.4, where an insufficient
vetting of parameters passed with the Prompt:Open IPC message between
child and parent processes can result in the non-sandboxed parent
process opening web content chosen by a compromised child process. When
combined with additional vulnerabilities this could result in executing
arbitrary code on the user's computer.

Impact
======

An attacker could use this vulnerability, combined with another one, to
bypass the sandbox and execute arbitrary code on the host.
