Stack-based buffer overflow in the Internet E-mail Auto-Protect feature in Symantec AntiVirus Corporate Edition before 10.1, and Client Security before 3.1, allows local users to cause a denial of service (service crash) via a long (1) To, (2) From, or (3) Subject header in an outbound SMTP e-mail message. NOTE: the original vendor advisory referenced CVE-2006-3456, but this was an error.

Security readout for executives and security teams

This flaw could let a local user crash Symantec’s email-scanning protection by sending an outbound email with an overly long To, From, or Subject header. The sourced impact is denial of service, not confirmed code execution. Business urgency depends on whether legacy Symantec endpoint products remain deployed. Exposure is most likely on legacy endpoints still running the named Symantec products below the fixed major versions, especially where Internet E-mail Auto-Protect processes outbound SMTP traffic. Treat this as a legacy hygiene issue unless affected products remain in use. If present, prioritize remediation because a local user could disable email scanning availability on endpoints. Mitigation focus: Inventory endpoints for the named legacy Symantec products and versions.; Upgrade Symantec AntiVirus Corporate Edition to 10.1 or later where applicable.; Upgrade Symantec Client Security to 3.1 or later where applicable..
