CVE-1999-1075: IBM Aix

Medium severity, CVSS 5.0. EPSS: 1.3% chance of exploitation in the next 30 days.

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.

Affected products

• IBM Aix: version 4.1.5 only
