AIX 5.3 TL 10 : bos.net.tcp.server (U823185)

High Nessus Plugin ID 44159

Synopsis

The remote AIX host is missing a vendor-supplied security patch.

Description

The remote host is missing AIX PTF U823185, which is related to the security of the package bos.net.tcp.server.

AIX 'named' is an implementation of BIND (Berkeley Internet Name Domain) providing server functionality for the Domain Name System (DNS) Protocol. AIX currently ships and supports three versions of BIND: 4, 8, and 9.

There is an error in the handling of dynamic update messages in BIND 9. A crafted update packet from a remote user can cause a master server to assert and exit. The successful exploitation of this vulnerability allows a remote, unauthenticated user to make a master DNS server assert and exit.

The following command is vulnerable :

/usr/sbin/named9.

Solution

Install the appropriate missing security-related fix.
