Arch Linux ASA-201706-24: Medium Severity Access Bypass in lxterminal-gtk3

Arch Linux Security Advisory ASA-201706-24
=========================================
Severity: Medium
Date    : 2017-06-22
CVE-ID  : CVE-2016-10369
Package : lxterminal-gtk3
Type    : access restriction bypass
Remote  : No
Link    : https://security.archlinux.org/AVG-264

Summary
======
The package lxterminal-gtk3 before version 0.3.0-2 is vulnerable to
access restriction bypass.

Resolution
=========
Upgrade to 0.3.0-2.

# pacman -Syu "lxterminal-gtk3>=0.3.0-2"

The problem has been fixed upstream but no release is available yet.

Workaround
=========
None.

Description
==========
unixsocket.c in lxterminal through 0.3.0 insecurely uses /tmp for a
socket file, allowing a local user to cause a denial of service
(preventing terminal launch), or possibly have other impact (bypassing
terminal access control).

Impact
=====
A local attacker might be able to cause a denial of service or bypass
the terminal access control to gain privileges or access sensitive
information.
