CVE-2005-1346: Multiple Symantec AntiVirus products, including Norton AntiVirus 2005 11.0.0, Web Security Web Security 3.0...

Security readout for executives and security teams

A specially crafted RAR archive could crash components in several legacy Symantec antivirus and mail/web security products on Windows. That could interrupt scanning and let malicious content avoid detection. The provided sources do not show current exploitation or a CVSS score. Exposure is most likely in legacy Windows environments still running the specifically listed Symantec antivirus, scan engine, web security, Domino, SMTP, or Exchange mail security versions. Modern environments are unlikely to be affected unless old products remain embedded in mail gateways, lab systems, or unsupported servers. Treat as a legacy exposure cleanup item with moderate urgency. Prioritize environments where these products inspect email, web, or shared-file traffic, because scanner failure can reduce malware detection at a control point. Mitigation focus: Check Symantec advisory guidance for fixed or unaffected builds.; Retire unsupported listed products where still present.; Update remaining Symantec products through vendor-supported channels..
