RHBA-2011:0921 - Bug Fix Advisory

Topic

An updated jwhois package that fixes one bug and adds one enhancement is now
available for Red Hat Enterprise Linux 6.

Description

The jwhois package provides a whois client, which is used to obtain information
about domain names and IP addresses from whois servers.

This update fixes the following bug:

• Previously, when querying a domain with the name length near the allowed limit

of 63 characters, and emitting command options to a whois server, the "whois"
command failed because both the domain name and command options were given to a
function responsible for translating Internationalized Domain Names (IDN) to
ASCII. The length of such command was greater than the allowed limit. This
update fixes this bug so that only the domain name is now translated after
executing the command. (BZ#682832)

As well, this update adds the following enhancement:

• Previously, jwhois did not contain the whois server details for the dotEmarat

extension. As a result, whois queries for these extensions were incorrectly
directed to whois.internic.net. With this update, the configuration file
correctly directs queries for the dotEmarat domains to whois.aeda.net.ae.
(BZ#664449)

All users of whois clients are advised to upgrade to this updated package, which
fixes this bug and adds this enhancement.
