Chapter 1. Package Updates
148
This update has been rated as having low security impact by the Red Hat Security Response Team.
LFTP is a sophisticated file transfer program for the FTP and HTTP protocols. Like bash, it has job
control and uses the readline library for input. It has bookmarks, built-in mirroring, and can transfer
several files in parallel. It is designed with reliability in mind.
It was discovered that lftp did not properly escape shell metacharacters when generating shell scripts
using the "mirror --script" command. A mirroring script generated to download files from a malicious
FTP server could allow an attacker controlling the FTP server to run an arbitrary command as the user
running lftp. (
CVE-2007-2348
1129
)
This update also fixes the following bugs:
• when using the "mirror" or "get" commands with the "-c" option, lftp did not check for some specific
conditions that could result in the program becoming unresponsive, hanging and the command
not completing. For example, when waiting for a directory listing, if lftp received a "226" message,
denoting an empty directory, it previously ignored the message and kept waiting. With this update,
these conditions are properly checked for and lftp no longer hangs when "-c" is used with "mirror" or
"get". (
BZ#422881
1130
)
• when using the "put", "mput" or "reput" commands over a Secure FTP (SFTP) connection,
specifying the "-c" option sometimes resulted in corrupted files of incorrect size. With this update,
using these commands over SFTP with the "-c" option works as expected, and transferred files are
no longer corrupted in the transfer process. (
BZ#434294
1131
)
• previously, LFTP linked to the OpenSSL library. OpenSSL's license is, however, incompatible with
LFTP's GNU GPL license and LFTP does not include an exception allowing OpenSSL linking. With
this update, LFTP links to the GnuTLS (GNU Transport Layer Security) library, which is released
under the GNU LGPL license. Like OpenSSL, GnuTLS implements the SSL and TLS protocols, so
functionality has not changed. (
BZ#458777
1132
)
• running "help mirror" from within lftp only presented a sub-set of the available options compared
to the full list presented in the man page. With this update, running "help mirror" in lftp presents
the same list of mirror options as is available in the Commands section of the lftp man page.
(
BZ#461922
1133
)
• LFTP imports gnu-lib from upstream. Subsequent to gnu-lib switching from GNU GPLv2 to GNU
GPLv3, the LFTP license was internally inconsistent, with LFTP licensed as GNU GPLv2 but
portions of the package apparently licensed as GNU GPLv3 because of changes made by the
gnu-lib import. With this update, LFTP itself switches to GNU GPLv3, resolving the inconsistency.
(
BZ#468858
1134
)
• when the "ls" command was used within lftp to present a directory listing on a remote system
connected to via HTTP, file names containing spaces were presented incorrectly. This update
corrects this behavior. (
BZ#504591
1135
)
• the default alias "edit" did not define a default editor. If EDITOR was not set in advance by the
system, lftp attempted to execute "~/.lftp/edit.tmp.$$" (which failed because the file is not set
to executable). The edit alias also did not support tab-completion of file names and incorrectly
interpreted file names containing spaces. The updated package defines a default editor (vi) in the
absence of a system-defined EDITOR. The edit alias now also supports tab-completion and handles
file names containing spaces correctly for both downloading and uploading. (
