The audit facility in the Security component in IBM DB2 UDB 9.5 before FP6a uses instance-level audit settings to capture connection (aka CONNECT and AUTHENTICATION) events in certain circumstances in which database-level audit settings were intended, which might make it easier for remote attackers to connect without discovery.

dasauto in IBM DB2 8 before FP18, 9.1 before FP8, 9.5 before FP4, and 9.7 before FP1 permits execution by unprivileged user accounts, which has unspecified impact and local attack vectors.

Unspecified vulnerability in IBM DB2 8 before FP17a, 9.1 before FP6a, and 9.5 before FP3a allows remote attackers to cause a denial of service (infinite loop) via a crafted CONNECT data stream.

Unspecified vulnerability in the server in IBM DB2 8 before FP17a, 9.1 before FP6a, and 9.5 before FP3a allows remote authenticated users to cause a denial of service (trap) via a crafted data stream.

Unspecified vulnerability in the JDBC Applet Server Service (aka db2jds) in IBM DB2 UDB 8 before Fixpak 17 allows remote attackers to cause a denial of service (service crash) via "malicious packets."

Unspecified vulnerability in the DB2 Administration Server (DAS) in the Core DAS function component in IBM DB2 9.1 before Fixpak 5 allows local users to gain privileges, aka a "FILE CREATION VULNERABILITY." NOTE: this may be the same as CVE-2007-5664.

Multiple stack-based buffer overflows in IBM DB2 9.1 before Fixpak 5 and 9.5 before Fixpak 1 allow remote attackers to cause a denial of service (system outage) via vectors related to (1) use of XQuery to issue statements; the (2) XMLQUERY, (3) XMLEXISTS, and (4) XMLTABLE statements; and the (5) sqlrlaka function.

The routine infrastructure component in IBM DB2 8 before FP17, 9.1 before FP5, and 9.5 before FP1 on Unix and Linux does not change the ownership of the db2fmp process, which has unknown impact and attack vectors.

Unspecified vulnerability in the CLR stored procedure deployment from IBM Database Add-Ins for Visual Studio in the Visual Studio Net component in IBM DB2 9.1 before Fixpak 5 and 9.5 before Fixpak 2 allows remote authenticated users to execute arbitrary code via unknown vectors.

The Downlevel DB2RA Support component in IBM DB2 9.1 before Fixpak 4a allows remote attackers to cause a denial of service (instance crash) via a crafted CONNECT data stream that simulates a V7 client connect request.
