Technical Description
The Symantec NAVOPTS.DLL ActiveX control (aka Symantec.Norton.AntiVirus.NAVOptions) 12.2.0.13, as used in Norton AntiVirus, Internet Security, and System Works 2005 and 2006, is designed for use only in application-embedded web browsers, which allows remote attackers to "crash the control" via unspecified vectors related to content on a web site, and place Internet Explorer into a "defunct state" in which remote attackers can execute arbitrary code in addition to other Symantec ActiveX controls, regardless of whether they are marked safe for scripting. NOTE: this CVE was inadvertently used for an E-mail Auto-Protect issue, but that issue has been assigned CVE-2007-3771.
Remediation
Check the references section for vendor advisories and patches from symantec. Update norton_antivirus to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
