- Systems running Oracle9i Database (Release 1 and 2)

- Systems running Oracle9i Application Server (Release 9.0.2 and 9.0.3)
Multiple vulnerabilities exist in Oracle software that may lead to execution of arbitrary code; the ability to read, modify, or delete information stored in underlying Oracle databases; or denial of service. All of these vulnerabilites were discovered by Next Generation Security Software Ltd.
Multiple vulnerabilities exist in Oracle software products. The majority of these vulnerabilities are buffer overflows.Oracle has published Security Alerts describing these vulnerabilities. If you use Oracle products listed in the "Systems Affected" section of this document, we strongly encourage you to review the following Oracle Security Alerts and apply patches as appropriate:
- Buffer Overflow in DIRECTORY parameter of Oracle9i Database Server
- Buffer Overflow in TZ_OFFSET function of Oracle9i Database Server
- Buffer Overflow in TO_TIMESTAMP_TZ function of Oracle9i Database Server
- Buffer Overflow in ORACLE.EXE binary of Oracle9i Database Server
- Two Vulnerabilities in Oracle9i Application Server
- Oracle9i Application Server Format String Vulnerability
- Oracle TO_TIMESTAMP_TZ Remote System Buffer Overrun
- ORACLE bfilename function buffer overflow vulnerability
- Oracle TZ_OFFSET Remote System Buffer Overrun
- Oracle unauthenticated remote system compromise
II. ImpactDepending on the vulnerability being exploited, an attacker may be able to execute arbitrary code; read, modify, or delete information stored in underlying Oracle databases; or cause a denial of service. The vulnerabilities in "ORACLE.EXE" (VU#953746) and the WebDAV modules (VU#849993, VU#511194) may be exploited prior to authentication.
Apply a patchSolutions for specific vulnerabilities can be found in the above referenced Oracle Security Alerts, NGSSoftware Insight Security Research Advisories, and individual CERT/CC Vulnerability Notes.
Mitigation StrategiesUntil a patch can be applied, the CERT/CC recommends that vulnerable sites
- disable unnecessary Oracle services
- run Oracle services with the least privilege
- restrict network access to Oracle services
