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.

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).

hostname via DHCP (CVE-2012-2321).
* An infinite loop error exists in client.c (CVE-2012-2322).
Impact
