-----BEGIN PGP SIGNED MESSAGE----- Internet Security Systems Security Brief August, 13, 2002 Remote Denial of Service Vulnerability in Oracle9i SQL*NET Synopsis: ISS X-Force has discovered a flaw in the debugging mechanism of Oracle9i. To exploit this vulnerability, attackers must send a specially crafted request to an Oracle9i SQL*NET listener. Due to an implementation flaw, Oracle9i does not handle the request correctly and fails. All Oracle9i installations are vulnerable to this attack. Impact: A successful attack on a vulnerable server can cause the SQL*NET listener to fail and crash. Database functionality cannot be restored until the listener is manually restarted. Affected Versions: Oracle9i 9.0.x Oracle9i 9.2 Note: All platforms for the affected versions are vulnerable.
