The remote AIX host is missing a vendor-supplied security patch.
The remote host is missing AIX PTF U843468, which is related to the security of the package bos.net.tcp.client. AIX could allow a remote attacker to cause a denial of service, caused by an error when the TCP large send offload option is enabled on a network interface. By sending a specially crafted sequence of packets, an attacker could exploit this vulnerability to cause a kernel panic.
