Stack-based buffer overflow in Oracle Net Services for Oracle Database Server 9i release 2 and earlier allows attackers to execute arbitrary code via a "CREATE DATABASE LINK" query containing a connect string with a long USING parameter.
Buffer overflow in ORACLE.EXE for Oracle Database Server 9i, 8i, 8.1.7, and 8.0.6 allows remote attackers to execute arbitrary code via a long username that is provided during login, as exploitable through client applications that perform their own authentication, as demonstrated using LOADPSP.
Multiple buffer overflows in Oracle 9i Database release 2, Release 1, 8i, 8.1.7, and 8.0.6 allow remote attackers to execute arbitrary code via (1) a long conversion string argument to the TOTIMESTAMPTZ function, (2) a long time zone argument to the TZOFFSET function, or (3) a long DIRECTORY parameter to the BFILENAME function.
