The remote Red Hat host is missing a security update.
The wget packages shipped with Red Hat Linux Advanced Server 2.1
contain a security bug which, under certain circumstances, can cause
local files to be written outside the download directory.
[Updated 09 Jan 2003] Added fixed packages for the Itanium (IA64)
[Updated 06 Feb 2003] Added fixed packages for Advanced Workstation
Versions of wget prior to 1.8.2-4 contain a bug that permits a
malicious FTP server to create or overwrite files anywhere on the
local file system.
FTP clients must check to see if an FTP server's response to the NLST
command includes any directory information along with the list of
filenames required by the FTP protocol (RFC 959, section 4.1.3).
If the FTP client fails to do so, a malicious FTP server can send
filenames beginning with '/' or containing '/../' which can be used to
direct a vulnerable FTP client to write files (such as .forward,
.rhosts, .shost, etc.) that can then be used for later attacks against
the client machine.
All users of wget should upgrade to the errata packages which are not
vulnerable to this issue.
Thanks to Steven M. Christey for his work in discovering this issue in
current FTP clients and for providing a patched FTP server to verify
the new packages.
