Oracle Database Server dbms_system.ksdwrt() Function Remote Overflow
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Unknown Vendor Verified

- 漏洞描述

Oracle Database Server contains a flaw that may allow a remote attacker to execute arbitrary code. The issue is due to the dbms_system.ksdwrt() function not properly sanitizing user input. If an attacker provides a specially crafted argument for the second argument of this function, a buffer overflow occurs potentially allowing code execution.

- 漏洞讨论

A remotely exploitable buffer overflow exists in Oracle Database Server.

The issue can be triggered when an overly long string is passed to an internal logging function. Authorized users could exploit this issue to execute arbitrary code in the context of the server process or to cause a denial of service.

This issue corresponds to one of the unspecified vulnerabilities mentioned in BID 10871 and addressed by Oracle Alert #68.

- 漏洞利用

Currently we are not aware of any exploits for this issue. If you feel we are in error or are aware of more recent information, please mail us at: <>.

- 解决方案

Oracle has released an alert (#68) and a patch to address these issues. Information regarding obtaining and applying an appropriate patch can be found at the following location:

It should be noted that a valid subscription to the metalink service is required in order to view this document.

It is reported that software conflicts may arise when these patches are installed against binaries that have already had patches installed. Additionally, although Oracle 9i 9.2.x.x database server is supported, it is reported that customers may be required to update to versions prior to applying these patches. This action might also be required for other releases and products. Customers are advised to contact the vendor for further information and support in regards to the installation of appropriate updates.

A message from "David Litchfield" <> is available that states that some of the vulnerabilities in alert #68 may not have been successfully fixed by Oracle. Users of affected packages should refer to the referenced message, and contact their vendor for further information on the status of fixes.
