Vulnerability Name:

CVE-1999-1075 (CCN-813)

Assigned:1998-03-18
Published:1998-03-18
Updated:2016-10-18
Summary:inetd in AIX 4.1.5 dynamically assigns a port N when starting ttdbserver (ToolTalk server), but also inadvertently listens on port N-1 without passing control to ttdbserver, which allows remote attackers to cause a denial of service via a large number of connections to port N-1, which are not properly closed by inetd.
