RHBA-2012:1354 - ftp bug fix update

Synopsis

ftp bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated ftp packages that fix four bugs are now available for Red Hat Enterprise Linux 6.

Description

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.

This update fixes the following bugs:

  • 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. (BZ#665337)

  • 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. (BZ#786004)

  • Previously, the ftp client could not be invoked to run directly in the active mode. This functionality has been added to the source code and documented in the manual page. The client can now be executed with an additional "-A" command line parameter and will run in the active mode. (BZ#849940)

  • Previously, the ftp client hung up when the ftp-data port (20) was not available (e.g. was blocked). The client then had to be terminated manually. Additional logic has been added to the source code. With this update, ftp has an internal timeout set to 30 seconds. If there is no answer from the server when this time has passed, ftp will now gracefully time out and not hang up. (BZ#852636)

All users of ftp are advised to upgrade to these updated packages, which fix these bugs.
