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.

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.

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.

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.
