The TNS Listener in Oracle 10g allows remote attackers to cause a denial of service (listener crash) via a malformed serviceregisterNSGR request containing a value that is used as an invalid offset for a pointer that references incorrect memory.

Oracle 10g Database Server stores the password for the SYSMAN account in cleartext in the world-readable emoms.properties file, which could allow local users to gain DBA privileges.

Oracle 10g Database Server, when installed with a password that contains an exclamation point ("!") for the (1) DBSNMP or (2) SYSMAN user, generates an error that logs the password in the world-readable postDBCreation.log file, which could allow local users to obtain that password and use it against SYS or SYSTEM accounts, which may have been installed with the same password.

Extproc in Oracle 9i and 10g does not require authentication to load a library or execute a function, which allows local users to execute arbitrary commands as the Oracle user.
