Discussion

Oracle 9i TNS Denial of Service Vulnerability

Oracle is a commercial relational database product. Oracle is available for the Unix, Linux, and Microsoft Windows platforms.

Reportedly, sending a one byte packet to the TNS Listener on port 1521 could cause the host to consume all available CPU, potentially leading to a denial of service.

This issue may stem from an originally discovered issue in Oracle Net8 (formerly Oracle SQL*Net). However this has not yet been confirmed.
