Exploit Public Vendor Verified, Coordinated Disclosure

- 漏洞描述

VirusScan NT contains a flaw that may cause a user to have out of date virus signatures, making remote context-dependent attacks more successful. The issue is due to the FTP-based update mechanism sometimes failing to properly update the antivirus signatures (in scan.dat), but still indicating that the signatures are updated. This gives the user a false sense of security and outdated signatures.

- 漏洞讨论

A vulnerability in Network Associates VirusScan for Windows NT stops it from updateting the virus signature definition files under certain conditions while it reports that it is up to date.

NAI's VirusScan features an option that allows the virus signature file to be updates automatically via FTP. A race condition in the code stops the program from correctly updating the definition file yet it fails to notice this error and updates the log as if the file was sucessufully updated and any subsequent updates will inform the user they are up to date. The error cannot be reproduced consistently.

To check that the file is being updated correctly go to the About box fromt he AntiVirus Console and read the latest date next to the text "Created On". If this date does not change after a manual or automatic update you are vulnerable.
