Buffer overflow in the TCP/IP listener in IBM DB2 Universal Database (UDB) before 8.1 FixPak 12 allows remote attackers to cause a denial of service (application crash) via a long MGRLVLLS message inside of an EXCSAT message when establishing a connection.

IBM DB2 Universal Database (UDB) before 8.2 FixPak 12 allows remote attackers to cause a denial of service (application crash) by sending "incorrect information ... regarding the package name/creator," which leads to a "memory overwrite."

Multiple unspecified vulnerabilities in IBM DB2 Universal Database (UDB) before 8.1 FixPak 12 allow remote attackers to cause a denial of service (application crash) via a (1) "long column list" in the (a) REPLACE INTO and (b) INSERT INTO portions of the LOAD command or a (2) large number of values in an IN clause, possibly related to a buffer overflow.

The (1) to_char and (2) to_date function in IBM DB2 8.1 allows local users to cause a denial of service (application crash) via an empty string in the second parameter, which causes a null pointer dereference.

Shared memory sections and events in IBM DB2 8.1 have default permissions of read and write for the Everyone group, which allows local users to gain unauthorized access, gain sensitive information, such as cleartext passwords, and cause a denial of service.

Stack-based buffer overflows in the (1) xmlvarcharfromfile, (2) xmlclobfromfile, (3) xmlfilefromvarchar, and (4) xmlfilefromclob function calls in IBM DB2 8.1 allow remote attackers to execute arbitrary code via a 94-byte second argument, which causes the return address to be overwritten with a pointer to the argument.

Certain XML functions in IBM DB2 8.1 run with the privileges of DB2 instead of the logged-in user, which allows remote attackers to create or overwrite files via (1) XMLFileFromVarchar or (2) XMLFileFromClob, or read files via (3) XMLVarcharFromFile or (4) XMLClobFromFile.

IBM DB2 Universal Database (UDB) 820 before version 8 FixPak 10 (s050811) allows remote authenticated users to cause a denial of service (application crash) by using a table function for an instance of snapshot_tbreorg, which triggers a trap in sqlnr_EStoE_action.

IBM DB2 Universal Database (UDB) 810 before ESE AIX 5765F4100 does not ensure that a user has execute privileges before permitting object creation based on routines, which allows remote authenticated users to gain privileges.

Stack-based buffer overflow in call in IBM DB2 7.x and 8.1 allows remote attackers to execute arbitrary code via a long libname.
