TNS Listener in Oracle Net Services for Oracle 9i 9.2.x and 9.0.x, and Oracle 8i 8.1.x, allows remote attackers to cause a denial of service (hang or crash) via a SERVICE_CURLOAD command.

Buffer overflows in the ApacheBench benchmark support program (ab.c) in Apache before 1.3.27, and Apache 2.x before 2.0.43, allow a malicious web server to cause a denial of service and possibly execute arbitrary code via a long response.

Cross-site scripting (XSS) vulnerability in the default error page of Apache 2.0 before 2.0.43, and 1.3.x up to 1.3.26, when UseCanonicalName is "Off" and support for wildcard DNS is present, allows remote attackers to execute script as other web page visitors via the Host: header, a different vulnerability than CAN-2002-1157.

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.

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.

The default configuration of Oracle 9i Application Server 1.0.2.x allows remote anonymous users to access sensitive services without authentication, including Dynamic Monitoring Services (1) dms0, (2) dms/DMSDump, (3) servlet/DMSDump, (4) servlet/Spy, (5) soap/servlet/Spy, and (6) dms/AggreSpy; and Oracle Java Process Manager (7) oprocmgr-status and (8) oprocmgr-service, which can be used to control Java processes.

PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allows remote attackers to cause a denial of service (crash) via an HTTP Authorization header without an authentication type.

PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allows remote attackers to bypass authentication for a Database Access Descriptor (DAD) by modifying the URL to reference an alternate DAD that already has valid credentials.
