Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
The netsnmp python module did not properly parse OID names which included name of MIBs 'like IF-MIB::ifTable'. In this update, regular expression for parsing OID names is fixed and the python module can properly parse names with names of MIBs.

Description of problem:
The regex in the python binding fails to account for colons in tags. So when attempting a Varbind on 'SNMPv2-SMI::enterprises.674.10892.1.300.10.1.11.1' it will be split into a "tag" of "SNMPv2-SMI" and an "iid" of "::enterprises.674.10892.1.300.10.1.11.1" which then fails in a get operation with a core dump.
Version-Release number of selected component (if applicable):
net-snmp-devel-5.5-31.el6.x86_64
net-snmp-5.5-31.el6.x86_64
net-snmp-python-5.5-31.el6.x86_64
net-snmp-libs-5.5-31.el6.x86_64
net-snmp-utils-5.5-31.el6.x86_64
Red Hat Enterprise Linux Server release 6.1 (Santiago)
Additional info:
The attached patch updates the regex to accommodate colons
