Buffer overflow in TNS Listener for Oracle 9i Database Server on Windows systems, and Oracle 8 on VM, allows local users to execute arbitrary code via a long SERVICE_NAME parameter, which is not properly handled when writing an error message to a log file.

SQL*NET listener for Oracle Net Oracle9i 9.0.x and 9.2 allows remote attackers to cause a denial of service (crash) via certain debug requests that are not properly handled by the debugging feature.

Transparent Network Substrate (TNS) Listener in Oracle 9i 9.0.1.1 allows remote attackers to cause a denial of service (CPU consumption) via a single malformed TCP packet to port 1521.

Oracle Oracle9i database server 9.0.1.x allows local users to access restricted data via a SQL query using ANSI outer join syntax.

Buffer overflows in PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allow remote attackers to cause a denial of service or execute arbitrary code via (1) a long help page request without a dadname, which overflows the resulting HTTP Location header, (2) a long HTTP request to the plsql module, (3) a long password in the HTTP Authorization, (4) a long Access Descriptor (DAD) password in the addadd form, or (5) a long cache directory name.

Oracle 9i Application Server stores XSQL and SOAP configuration files insecurely, which allows local users to obtain sensitive information including usernames and passwords by requesting (1) XSQLConfig.xml or (2) soapConfig.xml through a virtual directory.

The default configuration of Oracle 9i Application Server 1.0.2.x running Oracle JSP or SQLJSP stores globals.jsa under the web root, which allows remote attackers to gain sensitive information including usernames and passwords via a direct HTTP request to globals.jsa.

Oracle 8i and 9i with PL/SQL package for External Procedures (EXTPROC) allows remote attackers to bypass authentication and execute arbitrary functions by using the TNS Listener to directly connect to the EXTPROC process.

The default configuration of the PL/SQL Gateway web administration interface in Oracle 9i Application Server 1.0.2.x uses null authentication, which allows remote attackers to gain privileges and modify DAD settings.

Oracle 9iAS 1.0.2.x compiles JSP files in the _pages directory with world-readable permissions under the web root, which allows remote attackers to obtain sensitive information derived from the JSP code, including usernames and passwords, via a direct HTTP request to _pages.
