RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHSA-2014:0151 0 normal SHIPPED_LIVE Low: wget security and bug fix update 2014-02-10 22:29:11 UTC

Description Petr Šplíchal 2012-06-20 12:54:24 UTC 
Description of problem:

When wget fetches a page which is redirected to another page it
uses the redirected page name for file creation which could be
something user is not expecting and could probably present a
security issue. This is correctly fixed in latest wget in RHEL7.

Version-Release number of selected component (if applicable):
wget-1.12-1.4.el6.x86_64

Steps to Reproduce:
1. Set up some redirection on the server
2. wget the redirected page
  
Actual results:

For example:
wget --max-redirect=40 http://localhost/wget/redir/00.html

And same problem when github archive uses as Source0 in rpm package for RHEL6.

Please, update wget.
