The (1) dbsnmp and (2) nmo programs in Oracle 8i, Oracle 9i, and Oracle IAS 9.0.2.0.1, on Unix systems, use a default path to find and execute library files while operating at raised privileges, which allows certain Oracle user accounts to gain root privileges via a modified libclntsh.so.9.0.
Stack-based buffer overflow in the PL/SQL EXTPROC functionality for Oracle9i Database Release 2 and 1, and Oracle 8i, allows authenticated database users, and arbitrary database users in some cases, to execute arbitrary code via a long library name.
