CVE-2007-6738: pyftpdlib Use of Insufficiently Random Values of port selection on PASV command

May 1, 2022 (updated October 21, 2024)

pyftpdlib before 0.1.1 does not choose a random value for the port associated with the PASV command, which makes it easier for remote attackers to obtain potentially sensitive information about the number of in-progress data connections by reading the response to this command.
