SuSE 11.1 Security Update : dhcpcd (SAT Patch Number 4316)

medium Nessus Plugin ID 53357

Synopsis

The remote SuSE 11 host is missing a security update.

Description

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)

This update also fixes the following non-security issues :

- 564441: e1000 and dhcpd hickup

- 579438: endless loop after adding wlan usb stick (with dhcp ip lease time infinity)

- 654649: dhcpcd ignores -G (--nogateway) option and sets default route

- 657402: dhcpcd sends RENEWAL as ethernet broadcast instead of unicast

- 668194: dhcp client not working properly in Xen domU due to partial checksum offload

- 672038: dhcpcd sends RENEWAL as ethernet broadcast instead of unicast

Solution

Apply SAT patch number 4316.
