Unknown "high risk" vulnerability in DB2 Universal Database 8.1 and earlier has unknown impact and attack vectors. NOTE: due to the delayed disclosure of details for this issue, this candidate may be SPLIT in the future. In addition, this may be a duplicate of other issues as reported by the vendor.

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.

Multiple buffer overflows in IBM DB2 Universal Database 8.1 may allow local users to execute arbitrary code via long command line arguments to (1) db2start, (2) db2stop, or (3) db2govd.

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.

IBM DB2 Universal Database 7 before FixPak 12 creates certain DMS directories with insecure permissions (777), which allows local users to modify or delete certain DB2 files.

Buffer overflow in sqllib/security/db2ckpw for IBM DB2 Universal Database 6.0 and 7.0 allows local users to execute arbitrary code via a long username that is read from a file descriptor argument.

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 generate_distfile procedure.

IBM DB2 7.2 before FixPak 10a, and earlier versions including 7.1, allows local users to overwrite arbitrary files and gain privileges via a symlink attack on (1) db2job and (2) db2job2.

Stack-based buffer overflow in IBM DB2 Universal Data Base 7.2 for Windows, before Fixpak 10a, allows attackers with "Connect" privileges to execute arbitrary code via the INVOKE command.

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.

Buffer overflow in db2dart in IBM DB2 Universal Data Base 7.2 before Fixpak 10 allows local users to gain root privileges via a long command line argument.

The DB2 Discovery Service for IBM DB2 before FixPak 10a allows remote attackers to cause a denial of service (crash) via a long packet to UDP port 523.

Buffer overflow in db2licm in IBM DB2 Universal Data Base 7.2 before Fixpak 10a allows local users to gain root privileges via a long command line argument.

IBM DB2 7.0 allows a remote attacker to cause a denial of service (crash) via a single byte to (1) db2ccs.exe on port 6790, or (2) db2jds.exe on port 6789.

IBM DB2 Universal Database version 6.1 creates an account with a default user name and password, which allows remote attackers to gain access to the database.

IBM DB2 Universal Database version 6.1 allows users to cause a denial of service via a malformed query.
