VAR-199906-0005

Vulnerability from variot - Updated: 2023-12-18 13:05

A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes. A vulnerability in the MacOS X Server may crash it while under heavy load. The vulnerability appears while stress testing a server running the Apache web server and 32 or more process are concurntly doing HTTP GET request to a CGI script in a loop. The system will panic and display a stack trace with ipc_task_init. Although the vulnerability is not related to web servering it can only be reproduced so far using this means
