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 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 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.

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 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.

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.

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.
