CVE-1999-0377: Process table attack in Unix systems allows a remote attacker to perform a denial of service by filling a m...

Security readout for executives and security teams

This CVE describes an old denial-of-service weakness in Unix systems where many network connections can consume the system process table. If successful, the host may be unable to start needed processes, disrupting services. The source bundle does not identify specific vendors, versions, patches, or current exploitation. Potential exposure is limited to Unix-like systems and network services whose connection handling can consume process table entries. The bundle does not name affected products, versions, or configurations, so exposure must be determined through local inventory and vendor documentation. Treat this as a legacy availability risk. Prioritize internet-facing or business-critical Unix systems, especially unsupported hosts. Because sources lack product-specific detail, the main action is exposure discovery and vendor-guided hardening, not emergency patching. Mitigation focus: Check vendor guidance for each supported Unix variant in your environment.; Apply vendor-supported updates or configuration recommendations where available.; Review network services that create or retain processes per connection..
