CA-2003-05 Multiple Vulnerabilities in Oracle Servers
Original
release date: February 19, 2003
Last revised: --
Source: CERT/CC
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

Insight Security Research Advisories describing these
issues are listed below:
* Oracle9i

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
