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 Huzaifa S. Sidhpurwala 2014-07-31 07:59:16 UTC 
The version of gmp in rhel-6, lacks the secure exponentiation function mpz_powm_sec ().

As per: https://gmplib.org/manual/Integer-Exponentiation.html the existing mpz_pown() is susceptible to timing attacks and should not be used.
Comment 3 Frantisek Kluknavsky 2014-10-30 15:29:27 UTC 
This should be fixed as a result of https://bugzilla.redhat.com/show_bug.cgi?id=1110689 - gmp will be rebased to 6.0.0.
I am not a security expert, could you please take a look if the new build satisfies your needs?
Comment 5 Frantisek Kluknavsky 2014-10-30 15:45:00 UTC 
Sorry for the misleading noise, rebase will affect RHEL7.
Comment 15 Red Hat Bugzilla 2023-09-14 02:12:18 UTC
