The routine infrastructure component in IBM DB2 8 before FP17, 9.1 before FP5, and 9.5 before FP1 on Unix and Linux does not change the ownership of the db2fmp process, which has unknown impact and attack vectors.

Stack-based buffer overflow in the AUTH_LIST_GROUPS_FOR_AUTHID function in IBM DB2 UDB 9.1 before Fixpak 3 allows attackers to cause a denial of service and possibly execute arbitrary code via a long argument.

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."

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) 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.

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.

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 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.

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

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.

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.

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.

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 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.
