CVE-2006-0263

Vulnerability

Multiple unspecified vulnerabilities exist in the Oracle Database server, as identified in the January 2006 Critical Patch Update (CPU). These affect versions 8.1.7.4, 9.0.1.5, 9.0.1.5 FIPS, 9.2.0.7, 10.1.0.5, and 10.2.0.1 [1]. The flaws reside in the Net Listener component (Vuln# DB09) and the Network Communications (RPC) component (Vuln# DB12, DB13) [1][2]. Details of the vulnerabilities are not disclosed, but they can be exploited remotely without authentication.

Exploitation

An attacker with network access to the Oracle Database server can exploit these vulnerabilities by sending crafted packets to the Net Listener or RPC services [1][2]. No prior authentication is required. The specific attack vectors are not publicly detailed, but they are remotely exploitable.

Impact

Successful exploitation can lead to a compromise of system confidentiality, integrity, and availability. For the Net Listener vulnerability, Oracle notes that compromising confidentiality and integrity is difficult, but availability is easily compromised [2]. Overall, an attacker may read or modify sensitive data or cause a denial-of-service condition [1][2].

Mitigation

Oracle released a Critical Patch Update in January 2006 addressing these vulnerabilities [1][2]. Apply the appropriate patches for each affected version from Oracle Support. No workarounds are documented.
