Netscape Communicator before version 4.73 and Navigator 4.07 do not properly validate SSL certificates, which allows remote attackers to steal information by redirecting traffic from a legitimate web server to their own malicious server, aka the "Acros-Suencksen SSL" vulnerability.

Security readout for executives and security teams

This is an old browser SSL certificate validation flaw. Affected Netscape clients could trust the wrong server after redirected traffic, letting an attacker impersonate a legitimate HTTPS site and steal submitted information. It matters mainly where legacy Netscape software still exists. Exposure is likely limited to legacy endpoints, archived virtual machines, kiosk systems, or old packaged browser deployments still using affected Netscape versions. Modern browsers are not identified as affected in the source bundle. Treat this as a legacy-risk cleanup item, not a current emergency, unless the organization still runs affected Netscape browsers in sensitive environments. If present, prioritize removal because HTTPS trust failure can expose credentials and confidential data. Mitigation focus: Remove affected Netscape browser versions from managed endpoints.; Upgrade legacy Netscape Communicator deployments to version 4.73 or later where applicable.; Review Red Hat advisory RHSA-2000:028 for packaged update guidance..
