Checks for version of Apache Detailed Explanation for this Vulnerability Assessment Summary : The remote web server is prone to multiple denial of service attacks. Description : The remote host appears to be running a version of Apache 2.x which is older than 2.0.50. There is denial of service flaw in Apache 2.0.x that can be triggered by sending a specially-crafted HTTP request, which results in the consumption of an arbitrary amount of memory. On 64-bit systems with more than 4GB virtual memory, this may lead to heap based buffer overflow. There is also a denial of service vulnerability in mod_ssl's 'ssl_io_filter_cleanup' function. By sending a request to vulnerable server over SSL and closing the connection before the server can send a response, a possible hacker can cause a memory violation that crashes the server.

Network Security Threat Level: Low / CVSS Base Score : 2 (AV:R/AC:L/Au:NR/C:N/A:P/I:N/B:N) Networks Security ID: 10619, 12877 Vulnerability Assessment Copyright: This script is Copyright (C) 2004 David Maciejak |
