4.193. vsftpd

Updated vsftpd packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The vsftpd package includes a Very Secure FTP (File Transfer Protocol) daemon.

Bug Fix

BZ#813567
Previously, the vsftpd daemon did not correctly handle a situation when it received the EADDRINUSE error from a TCP port which vsftpd was listening on. In such a case, vsftpd immediately sent an error message to an FTP client instead of retrying to use the port. This update modifies error handling of vsftpd so that the daemon now retries to use the port before sending the error message to the FTP client in this scenario.
All users of vsftpd are advised to upgrade to these updated packages, which fix this bug.
Updated vsftpd packages that fix multiple bugs are now available for Red Hat Enterprise Linux 5.
The vsftpd packages provide the VSFTP (Very Secure File Transfer Protocol) daemon.

Bug Fixes

BZ#795393
Prior to this update, the "local_max_rate" option did not work as expected. As a consequence, the transmission speed was significantly lower. This update extends the types of variables for calculating and accumulating the amount of transferred data and postpones the start of evaluation after the tenth.
BZ#799245
Prior to this update, the "ls" command failed to handle the wildcard character "?" correctly. This update modifies the "ls" code so that the "ls" command can now uses the wildcard character "?" as expected.
BZ#804078
Prior to this update, the file transfer on a TLS connection failed after transferring the first files when the "ssl_request_cert" option used the default setting "YES". This update modifies the underlying code so that the file transfer completes as expected.
BZ#809450
Prior to this update, the vsftpd daemon did not correctly handle "EADDRINUSE" errors received from a TCP port on which vsftpd was listening. As a consequence, vsftpd immediately sent an error message to an FTP client instead of retrying to use the port. This update modifies the error handling of vsftpd so that the daemon now retries the port before sending the error message to the FTP client.
BZ#845051
Prior to this update, the vsftpd daemon failed with the message "500 OOPS: vsf_sysutil_bind" when the ports from the range configured for passive mode were occupied. This could occur when repeating the "ls" command on the empty sub-directory in the FTP client. The updated daemon is able to reuse ports from the approved range that are in the state TIME_WAIT and the described failure is no more observed.
All users of vsftpd are advised to upgrade to these updated packages, which fix these bugs.
