Stack-based buffer overflow in the SMTP service support in vsmon.exe in Zone Labs ZoneAlarm before 4.5.538.001, ZoneLabs Integrity client 4.0 before 4.0.146.046, and 4.5 before 4.5.085, allows remote attackers to execute arbitrary code via a long RCPT TO argument.

Security readout for executives and security teams

This is an old remote code execution flaw in Zone Labs desktop security software. A maliciously long SMTP recipient field could crash or take control of the affected protection process. Modern exposure should be uncommon, but any legacy installation handling SMTP traffic deserves quick verification. Exposure is limited to systems still running the named legacy Zone Labs versions with SMTP processing reachable by untrusted mail traffic. The source bundle does not establish current widespread deployment or internet-scale exposure. Prioritize remediation if these products remain in production, especially near email flows. For most organizations, this should be a legacy-asset cleanup item rather than a broad emergency unless inventory confirms vulnerable deployments. Mitigation focus: Upgrade ZoneAlarm to 4.5.538.001 or later if still deployed.; Upgrade Integrity 4.0 to 4.0.146.046 or later.; Upgrade Integrity 4.5 to 4.5.085 or later..
