CVE-1999-0752
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDenial of service in Netscape Enterprise Server via a buffer overflow in the SSL handshake.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceBuffer overflow vulnerability in Netscape Enterprise Server's SSL handshake implementation allows remote attackers to cause a denial of service via specially crafted SSL handshake messages.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Netscape Enterprise Server is installedSearch for Netscape Enterprise Server binaries, directories, or services on the system. Common locations include /opt/netscape, /usr/netscape, or check system services for 'netscape' or 'enterprise' entries.Affected if Netscape Enterprise Server is present on the system
-
Verify SSL is enabledCheck the server configuration for SSL-enabled virtual servers or listen sockets. Look for SSL-related configuration files in the server root directory, typically in the 'https-secure' or 'https' directory.Affected if SSL is configured and the server accepts HTTPS connections
-
Confirm network exposureDetermine if the SSL port (default 443) is listening and accessible from network sources. Use 'netstat' or 'ss' commands to check for listening ports and verify firewall rules.Affected if The SSL-enabled Netscape Enterprise Server is accessible from network sources
-
Check running processesIdentify any running Netscape Enterprise Server processes using 'ps' command or system process monitoring tools.Affected if Netscape Enterprise Server processes are actively running and serving SSL connections
The environment is affected if Netscape Enterprise Server with SSL enabled is installed and running, as all versions of this legacy software contain the buffer overflow in the SSL handshake implementation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince Netscape Enterprise Server is obsolete legacy software from the late 1990s, the primary remediation is migration to a supported modern web server (such as Apache HTTP Server, Nginx, or IIS) with current SSL/TLS support. If legacy dependencies prevent migration, consider network-level filtering or isolation of the affected system.
