Apache < 2.0.50 Input Header Folding and mod_ssl DoS
Medium Nessus Network Monitor Plugin ID 2744
Synopsis
The remote host is vulnerable to a Denial of Service (DoS) attack.
Description
The remote host is using a version of the Apache web server that is less than 2.0.50. This version is vulnerable to two (2) remote Denial of Service (DoS) attacks. The first issue stems from a failure to properly manage memory and could lead to the consumption of massive amounts of memory and, alledgedly,a potential heap overflow. The second issue stems from mod_ssl's inability to handle sessions that terminate before any bytes of data have been sent. This second flaw results in a memory violation that leads to a loss of availability to valid users.
Solution
Upgrade to Apache 2.0.50 or higher.
