Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2000-0227. PoCs published by Jay Fenlason.

AI-analyzed exploit summary This exploit demonstrates a denial of service vulnerability in Linux kernels by creating successive Unix domain sockets, ignoring limits set in /proc/sys/net/core/wmem_max. It sends a large buffer to /dev/log, causing a DoS in vulnerable kernel versions.

Description

The Linux 2.2.x kernel does not restrict the number of Unix domain sockets as defined by the wmem_max parameter, which allows local users to cause a denial of service by requesting a large number of sockets.
