RHBA-2015:2137 - nmap bug fix update
Synopsis
nmap bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated nmap packages that fix two bugs are now available for Red Hat Enterprise Linux 7.
Description
The nmap packages provide a network exploration utility and a security scanner.
This update fixes the following bugs:
-
Previously, the ncat utility printed debug messages even when verbose mode was not enabled. As a consequence, after connecting through an HTTP proxy, a debug message was displayed together with the received data, which could interfere with the automated processing of standard output. With this update, ncat prints debug messages only in verbose mode as expected. (BZ#1134412)
-
Previously, when a host machine had both an IPv4 and IPv6 address, the ncat utility only used one of these addresses when connecting. The utility did not attempt to connect to the other address if the first attempted address was unreacheable, and the connection failed. The ncat connection code has been updated to use other addresses obtained by host name resolution after it fails to reach the first attempted address. As a result, ncat is able to connect even when one of the host machine IP addresses is unreacheable. (BZ#1192143)
Users of nmap are advised to upgrade to these updated packages, which fix these bugs.
Solution
Before applying this update, make sure all previously released errata relevant to your system have been applied.
