IDefense notified Symantec of a vulnerability in NAVEX15.SYS and NAVENG.SYS, two device drivers which are part of Symantecís anti-virus engine. A specially crafted IRP could be sent to the IOCTL handler function which could allow memory to be overwritten because the address space was not properly validated. A successful exploit could potentially allow a local attacker to execute code of their choice with kernel level privileges.
Symantec engineers verified that the vulnerability exists in NAVEX15.SYS and NAVENG.SYS, and have released solutions for the problem. The solution is available in NAVEX15.SYS and NAVENG.SYS version 20061.3.0.12 and later. To obtain the update, users should update their virus definitions to October 4, 2006 revision 9 or later.
Norton AntiVirus product users can obtain this update by running LiveUpdate, or downloading and running the Intelligent Updater. Enterprise customers can run LiveUpdate, or follow their standard corporate process for updating virus definitions.
Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue.
As part of normal best practices, Symantec recommends a multi-layered approach to security:
- Run under the principle of least privilege where possible.
- Keep all operating systems and applications updated with the latest vendor patches.
- Run a personal firewall and an antivirus application with current updates to provide multiple points of detection and protection from inbound and outbound threats.
- Be cautious of attachments and executables delivered via email and be cautious of browsing unknown/untrusted websites or opening unknown/untrusted URL links.
- Do not open unidentified attachments or executables from unknown sources or that you didn't request or were unaware of.
- Always err on the side of caution. Even if the sender is known, the source address may be spoofed.
- If in doubt, contact the sender to confirm they sent it and why before opening the attachment. If still in doubt, delete the attachment without opening it.
