IBM DB2 Universal Database (UDB) 810 before version 8 FixPak 10 allows remote authenticated users to cause a denial of service (db2jd service crash) by "connecting from a downlevel client."
Stack-based buffer overflow in JDBC Applet Server in IBM DB2 8.1 allows remote attackers to execute arbitrary by connecting and sending a long username, then disconnecting gracefully and reconnecting and sending a short username and an unexpected db2java.zip version, which causes a null terminator to be removed and leads to the overflow.
Stack-based buffer overflow in the SATENCRYPT function in IBM DB2 8.1, when Satellite Administration (SATADMIN) is enabled, allows remote attackers to execute arbitrary code via a long parameter.
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.
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.
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.
