Updated ftp packages that fix three bugs are now available for Red Hat Enterprise Linux 6.
The ftp packages provide the standard UNIX command line File Transfer Protocol (FTP) client. FTP is a widely used protocol for transferring files over the Internet, and for archiving files.
- Previously, the command line width in the ftp client was limited to 200 characters. With this update, the maximum possible length of the FTP command line is extended to 4296 characters.
- Prior to this update, "append", "put", and "send" commands were causing system memory to leak. The memory holding the ftp command was not freed appropriately. With this update, the underlying source code has been improved to correctly free the system resources and the memory leaks are no longer present.
- Previously, if a macro longer than 200 characters was defined and then used after a connection, the ftp client crashed due to a buffer overflow. With this update, the underlying source code was updated and the buffer that holds memory for the macro name was extended. It now matches the length of the command line limit mentioned above. As a result, the ftp client no longer crashes when a macro with a long name is executed.
All users of ftp are advised to upgrade to these updated packages, which fix these bugs.
Updated tftp packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The Trivial File Transfer Protocol (TFTP) is normally used only for booting diskless workstations. The tftp package provides the user interface for TFTP, which allows users to transfer files to and from a remote machine. The tftp-server package provides the server for TFTP which allows users to transfer files to and from a remote machine.
- When the small files were transferred and the "-v" option was enabled, the tftp client printed incorrect statistics about the transfer. This update fixes printing of the transfer statistics.
- The tftpd daemon did not correctly handle the utimeout option value. If a client specified a utimeout value within the permitted range, it caused the tftpd process to crash. This crash only affected the current tftp request.
All users of tftp and tftp-server should upgrade to these updated packages, which fix these bugs.
