RHBA-2012:1436 - ftp bug fix update

Synopsis

ftp bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated ftp packages that fix three 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#871059)

  • 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#871071)

  • 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. (BZ#871546)

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