Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions: Apache versions prior to 2.0.47

Description: The issue occurs when the FTP proxy server fails to create an IPv6 socket, leading to an infinite loop and causing a denial of service due to CPU consumption. This happens when a client requests that the proxy ftp connect to a ftp server with an IPv6 address and the proxy is unable to create an IPv6 socket.

Recommendations: For Apache versions prior to 2.0.47, update to version 2.0.47 or later to resolve the issue. As a temporary workaround, consider restricting access to the FTP proxy server to minimize the risk of exploitation.
