Synopsis
========

Multiple vulnerabilities have been found in ConnMan, allowing attackers
to execute arbitrary code or cause Denial of Service.

Background
==========

ConnMan provides a daemon for managing Internet connections.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/connman < 1.0-r1 >= 1.0-r1

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

Multiple vulnerabilities have been found in ConnMan:

* Errors in inet.c and rtnl.c prevent ConnMan from checking the origin
of netlink messages (CVE-2012-2320).
* ConnMan does not properly check for shell escapes when requesting a
hostname via DHCP (CVE-2012-2321).
* An infinite loop error exists in client.c (CVE-2012-2322).

Impact
======

A remote attacker could execute arbitrary code with the privileges of
the process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All ConnMan users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/connman-1.0-r1"
