[Remi Gacogne]

Arch Linux Security Advisory ASA-201706-25
==========================================

Severity: Medium
Date    : 2017-06-22
CVE-ID  : CVE-2016-10369
Package : lxterminal
Type    : access restriction bypass
Remote  : No
Link    : https://security.archlinux.org/AVG-264

Summary
=======

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

Resolution
==========

Upgrade to 0.3.0-2.

# pacman -Syu "lxterminal>=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.
