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.

Description Andrew Cathrow 2011-08-22 12:58:41 UTC 
Alan - as per rhev-devel email. Reported during beta

rhn.py uses string instead of sequence for args in subprocess.Popen which can lead to errors w.r.t. string escaping.

Comment 2 Joey Boggs 2011-08-23 17:43:46 UTC 

rhn/proxy user/password  are now single quoted to escape the characters

Some issues with a sequence. subprocess.Popen handles sequenced args as shell arguments rather than arguments to the program being called. No reason to create a list to have it rejoined in the end as a string. Can easily fix with single quotes on user managed options that could possibly have special characters and spaces.

Actually, there's a reason: list2cmdline should do proper quoting for you,
so it's best to send args as a list.
Comment 9 Joey Boggs 2011-08-30 16:42:41 UTC 
quoting around the password where we need quotes gets mangled when quotes are in the password itself all other bad characters are fine. Even escaping them ahead of time makes the situation worse. any ideas?

list2cmdline put into sample script with output

Comment 10 Alan Pevec 2011-08-30 21:58:13 UTC 
Not sure I understand, afaict list2cmdline does correct thing, don't escape or quote anything, just send it as a list to Popen and it will quote/escape as needed.

How did you create those?
When I tried to put space in RHN Hosted it said:
Password must be ASCII and cannot contain the following special characters (") (<) (>) (space)
