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 Clemens Lang 2023-02-14 15:34:20 UTC
Description of problem:
Using EVP_PKEY_CTX_new_from_name(NULL, "DHX", NULL), EVP_PKEY_fromdata_init(ctx) and EVP_PKEY_fromdata(ctx, &pkey, EVP_PKEY_KEYPAIR, params) with params containing a 512-bit DHX keypair, a short keypair can be created and will pass EVP_PKEY_public_check() and EVP_PKEY_private_check().

This should not work in FIPS mode, and OpenSSL should reject import of a short key or provide an explicit indicator to check for this.


Version-Release number of selected component (if applicable):
openssl-3.0.1-46.el9_0

How reproducible:
Run the attached reproducer provided by the lab.

Steps to Reproduce:
1. gcc -std=c99 -Wall -Werror -pedantic -D_XOPEN_SOURCE=600 -o dhver dhver.c -lcrypto
2. ./dhver

Actual results:
This is OpenSSL 3.0.1 14 Dec 2021 (0x30000010).
FIPS enabled: 1
All operations finished successfully!

Expected results:
Failure.
