Oracle Database Server 10g Release 2 allows local users to execute arbitrary SQL queries via the GET_DOMAIN_INDEX_METADATA function in the DBMS_EXPORT_EXTENSION package. NOTE: this issue was originally linked to DB05 (CVE-2006-1870), but a reliable third party has claimed that it is not the same issue. Based on details of the problem, the primary issue appears to be insecure privileges that facilitate the introduction of SQL in a way that is not related to special characters, so this is not "SQL injection" per se.
Directory traversal vulnerability in Oracle Database Server 8i and 9i allows remote attackers to read or rename arbitrary files via "\\.\\.." (modified dot dot backslash) sequences to UTL_FILE functions such as (1) UTL_FILE.FOPEN or (2) UTL_FILE.frename.
Multiple buffer overflows in the XML Database (XDB) functionality for Oracle 9i Database Release 2 allow local users to cause a denial of service or hijack user sessions.
