CVE-2005-0144: Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL refer...

Security readout for executives and security teams

This is an old browser trust-indicator flaw. Firefox before 1.0 and Mozilla before 1.7.5 could show the secure lock icon in a misleading view-source scenario while an insecure page loaded, making phishing pages look more trustworthy than they were. Exposure is mainly legacy workstations, kiosks, lab systems, or archived Linux builds still running Firefox before 1.0 or Mozilla before 1.7.5. Normal modern desktop fleets are unlikely to be affected unless unsupported browser packages remain installed. Treat this as a legacy hygiene issue unless old browsers are still present. If they are, prioritize removal because the flaw weakens user trust cues and can support credential phishing against sensitive services. Mitigation focus: Remove or upgrade Firefox versions before 1.0 and Mozilla versions before 1.7.5.; Apply relevant vendor or distribution advisories, including Red Hat updates where applicable.; Block unsupported legacy browsers from accessing sensitive internal or identity applications..
