openSUSE Security Update : dhcpcd (openSUSE-SU-2011:0385-1)

medium Nessus Plugin ID 53708

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update fixes the following security issue :

A rogue DHCP server could instruct clients to use a host name that contains shell meta characters. Since many scripts in the system do not expect unusal characters in the system's host name the DHCP client needs to sanitize the host name offered by the server (CVE-2011-0996).

Note this update is actually just a re-release of the previous one.
The security fix made dhcpcd crash if the DHCP server sent a SIP option that was not decodable. This update also allows spaces in the domain name option again as some DHCP servers abuse the option as DNS search list.

Solution

Update the affected dhcpcd package.
