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.

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 NNSTAT (aka SYSPROC.NNSTAT) procedure in IBM DB2 8 before FP16, 9.1 before FP4a, and 9.5 before FP1 on Windows allows remote authenticated users to overwrite arbitrary files via the log file parameter.

IBM DB2 8 before FP18, 9.1 before FP8, 9.5 before FP4, and 9.7 before FP2 does not perform the expected drops of certain table functions upon a loss of privileges by the functions' definers, which has unspecified impact and remote attack vectors.

The DB2DART program in IBM DB2 9.1 before FP9, 9.5 before FP6, and 9.7 before FP2 allows attackers to bypass intended file access restrictions via unspecified vectors related to overwriting files owned by an instance owner.

Buffer overflow in the DB2 Administration Server (DAS) component in IBM DB2 9.1 before FP10, 9.5 before FP7, and 9.7 before FP3 on Linux, UNIX, and Windows allows remote attackers to execute arbitrary code via unspecified vectors.

Integer signedness error in the db2dasrrm process in the DB2 Administration Server (DAS) in IBM DB2 9.1 through FP11, 9.5 before FP9, and 9.7 through FP5 on UNIX platforms allows remote attackers to execute arbitrary code via a crafted request that triggers a heap-based buffer overflow.
