Synopsis
=======
Multiple vulnerabilities have been found in ConnMan, allowing attackersto 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"
