Directory traversal vulnerability in extproc in Oracle 9i and 10g allows remote attackers to access arbitrary libraries outside of the $ORACLE_HOME\bin directory.

Buffer overflow in extproc in Oracle 10g allows remote attackers to execute arbitrary code via environment variables in the library name, which are expanded after the length check is performed.

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.

Multiple SQL injection vulnerabilities in PL/SQL procedures that run with definer rights in Oracle 9i and 10g allow remote attackers to execute arbitrary SQL commands and gain privileges via (1) DBMS_EXPORT_EXTENSION, (2) WK_ACL.GET_ACL, (3) WK_ACL.STORE_ACL, (4) WK_ADM.COMPLETE_ACL_SNAPSHOT, (5) WK_ACL.DELETE_ACLS_WITH_STATEMENT, or (6) DRILOAD.VALIDATE_STMT.
