* Errors in inet.c and rtnl.c prevent ConnMan from checking the origin |
| 40 |
of netlink messages (CVE-2012-2320). |
| 41 |
* ConnMan does not properly check for shell escapes when requesting a |
| 42 |
hostname via DHCP (CVE-2012-2321). |
| 43 |
* An infinite loop error exists in client.c (CVE-2012-2322). |
