Some vulnerabilities have been reported in IBM DB2, where some have an unknown impact and others can be exploited by malicious, local users to gain escalated privileges, and by malicious people to cause a DoS (Denial of Service) and disclose potentially sensitive information.

1) An unspecified error in "SQLNLS_UNPADDEDCHARLEN()" can be exploited to trigger a segmentation fault within a DB2 server.

2) Views and triggers are not dropped and marked inoperative within the Native Managed Provider for .NET if the definer cannot maintain the objects.

3) An unspecified error in the Sort/List services can be exploited to disclose password-related connection string keyword values.

4) An unspecified error related to DAS can be exploited to write to arbitrary files and gain root privileges.

The vulnerabilities are reported in versions prior to 9.1 FP6. Vulnerabilities #2 and #3 are reported in versions prior to 9.5 FP2.
