* Systems running Oracle 8i
A vulnerability in Oracle 8i allows remote intruders to assume control
of database servers running on victim machines. If the Oracle server
is running on a Windows system, an intruder may also be able to gain
contol of the underlying operating system.
The COVERT labs at PGP Security have discovered a buffer overflow
vulnerability in Oracle 8i that allows intruders to execute arbitrary
code with the privileges of the TNS listener process. The
vulnerability occurs in a section of code that is executed prior to
authentication, so an intruder does not require a username or
For more information, see the COVERT Labs Security Advisory, available
An intruder who exploits the vulnerability can remotely execute
arbitrary code. On UNIX systems, this code runs as the 'oracle' user.
If running on Windows systems, the intruder's code will run in the
Local System security context.
In either case, the attacker can gain control of the database server
on the victim machine. On Windows systems, the intruder can also gain
administrative control of the operating system.
Install a patch from Oracle. More information is available in
Oracle has issued an alert for this vulnerability at
Oracle has fixed this potential security vulnerability in the Oracle9i
database server. Oracle is in the process of backporting the fix to
