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 RHBA-2011:1658 0 normal SHIPPED_LIVE python-netaddr bug fix update 2011-12-06 00:50:23 UTC

Description Jakub Hrozek 2011-06-03 08:25:41 UTC 
+++ This bug was initially created as a clone of Bug #709701 +++

Description of problem:
If an IPNetwork object is instantiated with bad data, the python-netaddr code tries to access an unbound local variable. It should raise an appropriate exception instead.

This means that a user of python-netaddr must check for all exceptions instead of just expecting netaddr.core.AddrFormatError.

Version-Release number of selected component (if applicable):
python-netaddr-0.7.5-2

How reproducible:
always

Steps to Reproduce:
1. python -c "import netaddr; netaddr.IPNetwork('3333/32')"
  
Actual results:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 919, in __init__
    implicit_prefix, flags)
  File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 782, in parse_ip_network
    value = ip._value
UnboundLocalError: local variable 'ip' referenced before assignment


Expected results:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/netaddr/ip/__init__.py", line 926, in __init__
    raise AddrFormatError('invalid IPNetwork %s' % addr)
netaddr.core.AddrFormatError: invalid IPNetwork 3333/32


Additional info:
Upstream was tracking this as issue #2 and #5 in github
