Official Description

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.

Technical Analysis

CVE-2003-0095 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
