Arch Linux Security Advisory ASA-201807-13
==========================================
Severity: High
Date : 2018-07-20
CVE-ID : CVE-2018-10900
Package : networkmanager-vpnc
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-739
Summary
=======
The package networkmanager-vpnc before version 1.2.6-1 is vulnerable to
privilege escalation.
Resolution
==========
Upgrade to 1.2.6-1.
# pacman -Syu "networkmanager-vpnc>=1.2.6-1"
The problem has been fixed upstream in version 1.2.6.
Workaround
==========
None.
Description
===========
When initiating a VPNC connection, Network Manager spawns a new vpnc
process and passes the configuration via STDIN. By injecting a \n
character into a configuration parameter, an attacker can coerce
Network Manager to set the Password helper option to an attacker
controlled executable file.
Impact
======
A local attacker is able to escalate privileges via a specially crafted
configuration file.
