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.

Additional info:

This issue appears to be identical to the one identified in https://bugzilla.redhat.com/show_bug.cgi?id=1347920 for RHEL 6

https://github.com/FreeRDP/FreeRDP/issues/3412

It seems it is fixable. I added some notes to the upstream bug report, however, I didn't have time to propose fix yet, sorry:
https://github.com/FreeRDP/FreeRDP/issues/3412#issuecomment-263958217

I proposed the following pull request:
https://github.com/FreeRDP/FreeRDP/pull/3877
which have been superseded by:
https://github.com/FreeRDP/FreeRDP/pull/3904
which will be hopefully merged upstream soon...

Just a note that FIPS encryption method is automatically used and NLA authentication is automatically disabled with this build if OpenSSL operates in FIPS mode. NLA can't be used, because FreeRDP implements only NTLM, which requires MD5, which isn't FIPS compliant.

Have tested on x86_64 system running in FIPS mode with freerdp-1.0.2-13.el7.x86_64 and got mentioned error:
md4_dgst.c(75): OpenSSL internal error, assertion failed: Digest MD4 forbidden in FIPS mode!
Aborted (core dumped)

After update to freerdp-1.0.2-14.el7.x86_64 it works fine.
