SuSE 10 Security Update : dhcpcd (ZYPP Patch Number 7452)

medium Nessus Plugin ID 53359

Language:

Synopsis

The remote SuSE 10 host is missing a security-related patch.

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)

Note: this is a re-release of the security update. The previous update caused the DHCP client to reject domain names with spaces. That behavior is RFC conform but in practice some DHCP servers use the domain name field to set the DNS search list. Spaces are allowed again now but future products may enforce RFC compliance again. DHCP server administrators are advised to check their server setup.

Solution

Apply ZYPP patch number 7452.
