Unspecified binaries in IBM DB2 8.x before 8.1 FixPak 15 and 9.1 before Fix Pack 2 allow local users to create or modify arbitrary files via unspecified environment variables related to "unsafe file access."

Stack-based buffer overflow in libdb2.so in IBM DB2 7.x and 8.1 allows local users to execute arbitrary code via a long DB2LPORT environment variable.

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 overflow in db2fmp in IBM DB2 7.x and 8.1 allows local users to execute arbitrary code via a long parameter.

IBM DB2 Universal Database (UDB) 820 before ESE AIX 5765F4100 allows remote authenticated users to cause a denial of service (CPU consumption) by "abnormally" terminating a connection, which prevents db2agents from being properly cleared.

IBM DB2 Database server running on Windows XP with Simple File Sharing enabled, allows remote attackers to bypass authentication and log on to the guest account without supplying a password.

Multiple stack-based buffer overflows in IBM DB2 7.x and 8.1 allow local users to execute arbitrary code via (1) a long third argument to the rec2xml function or (2) a long filename argument to the generatedistfile procedure.

IBM DB2 7.1 and 8.1 allow the bin user to gain root privileges by modifying the shared libraries that are used in setuid root programs.

DB2 8.1 remote command server (DB2RCMD.EXE) executes the db2rcmdc.exe program as the db2admin administrator, which allows local users to gain privileges via the DB2REMOTECMD named pipe.

Stack-based buffer overflow in IBM DB2 Universal Data Base 7.2 before Fixpak 10 and 10a, and 8.1 before Fixpak 2, allows attackers with "Connect" privileges to execute arbitrary code via a LOAD command.
