Oracle Database 8i, 9i, and 10g allow remote authenticated users to execute arbitrary SQL statements in the context of the SYS user and bypass audit logging, including statements to create new privileged database accounts, via a modified AUTHALTERSESSION attribute in the authentication phase of the Transparent Network Substrate (TNS) protocol. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that this issue has been addressed by Oracle. It is possible that this is the same issue as Oracle Vuln# DB18 from the January 2006 CPU, in which case this would be subsumed by CVE-2006-0265.

SQL injection vulnerability in the SYS.DBMSMETADATAUTIL package in Oracle Database 10g, and possibly earlier versions, might allow remote attackers to execute arbitrary SQL commands via unknown vectors. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that this issue has been addressed by Oracle. It is possible that this is the same issue as Oracle Vuln# DB05 from the January 2006 CPU, in which case this would be subsumed by CVE-2006-0260. However, there are some inconsistencies that make this unclear, and there is also a possibility that this is related to DB06, which is subsumed by CVE-2006-0259.
