IBM DB2 Universal Database (UDB) 810 before 8.1 FP10 allows remote authenticated users to cause a denial of service (application crash) via (1) certain equality predicates that trigger self-removal, aka IY70808; and (2) a query with more than 32000 elements in the IN-list, aka LI70817.

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

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.

IBM DB2 Universal Database (UDB) 820 before 8.2 FP10 allows remote authenticated users to cause a denial of service (disk consumption) via a hash join (hsjn) that triggers an infinite loop in sqlri_hsjnFlushBlocks.

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.

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.

Unknown vulnerability in IBM DB2 8.1.4 through 8.1.9 and 8.2.0 through 8.2.2 allows local users with SELECT privileges to conduct unauthorized activities and insert, update or delete table contents.

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.
