Summary
Red Hat Security Advisory: : : : Updated wget packages fix directory traversal bug
Notes
Topic
The wget packages shipped with Red Hat Linux 6.2 through 8.0 contain a
security bug which, under certain circumstances, can cause local files to
be written outside the download directory.
[Updated 10 July 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems
Details
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 Red Hat Linux users using wget < 1.8.2-4 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.
