A complete revision history can be found at the end of this file.
Systems Affected
* Systems running Oracle9i Database (Release 1 and 2)
* Systems running Oracle8i Database v 8.1.7
* Systems running Oracle8 Database v 8.0.6
* Systems running Oracle9i Application Server (Release 9.0.2
and 9.0.3)
Overview
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.
I. Description
Multiple vulnerabilities exist in Oracle9i Application
Server,
Oracle9i Database, and Oracle8i Database. 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
http://otn.oracle.com/deploy/security/pdf/2003alert48.pdf
* Buffer Overflow in TZ_OFFSET function of Oracle9i Database Server
http://otn.oracle.com/deploy/security/pdf/2003alert49.pdf
* Buffer Overflow in TO_TIMESTAMP_TZ function of Oracle9i
Database Server
http://otn.oracle.com/deploy/security/pdf/2003alert50.pdf
* Buffer Overflow in ORACLE.EXE binary of Oracle9i Database Server
http://otn.oracle.com/deploy/security/pdf/2003alert51.pdf
* Two Vulnerabilities in Oracle9i Application Server
http://otn.oracle.com/deploy/security/pdf/2003alert52.pdf
NGSSoftware Insight Security Research Advisories describing
these
issues are listed below:
* Oracle9i Application Server Format String Vulnerability
http://www.nextgenss.com/advisories/ora-appservfmtst.txt
* Oracle TO_TIMESTAMP_TZ Remote System Buffer Overrun
http://www.nextgenss.com/advisories/ora-tmstmpbo.txt
* ORACLE bfilename function buffer overflow vulnerability
http://www.nextgenss.com/advisories/ora-bfilebo.txt
* Oracle TZ_OFFSET Remote System Buffer Overrun
http://www.nextgenss.com/advisories/ora-tzofstbo.txt
* Oracle unauthenticated remote system compromise
http://www.nextgenss.com/advisories/ora-unauthrm.txt
The CERT/CC has published vulnerability notes for each of these
issues
as well. The vulnerability in Oracle's mod_dav module (VU#849993)
has
been as assigned CVE ID CAN-2002-0842.
II. Impact
Depending 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.
III. Solution
Apply a patch
Solutions 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 Strategies
Until 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
