Insight
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)
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)
* 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)
* 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)
* 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)
* 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 a ...
