3. Problem description:

GNU Wget is a file retrieval utility that can use either the HTTP or
FTP protocols.

A bug was found in the way wget writes files to the local disk. If a
malicious local user has write access to the directory wget is saving a
file into, it is possible to overwrite files that the user running wget
has write access to. (CAN-2004-2014)

A bug was found in the way wget filters redirection URLs. It is possible
for a malicious Web server to overwrite files the user running wget has
write access to. Note: in order for this attack to succeed the local
DNS would need to resolve ".." to an IP address, which is an unlikely
situation. (CAN-2004-1487)

A bug was found in the way wget displays HTTP response codes. It is
possible that a malicious web server could inject a specially crafted
terminal escape sequence capable of misleading the user running wget.
(CAN-2004-1488)

Users should upgrade to this updated package, which contains a version of
wget that is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

144214 - CAN-2004-1487 Several wget vulnerabilities (CAN-2004-1488)
157498 - CAN-2004-2014 wget symlink race
165782 - wget man page incomplete
