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the product is no longer active in Red Hat Bugzilla.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.
Cause:
The FIPS_selftest() library call tries to perform operations that are forbidden for a library working in FIPS mode.
Consequence:
Application calling the method fails FIPS_selftest and reports error or crashes.
Fix:
FIPS_selftest() updated to perform only operations allowed in FIPS mode.
Please note that FIPS_selftest() is not a part of API of the current FIPS module. Calling it is not necessary for FIPS compliance. OpenSSL automatically performs self-tests when it detects that the system is running in FIPS mode.
Result:
Applications that call FIPS_selftest() no longer crash.
Description of problem:
The FIPS_selftest() routine fails if the system is in FIPS mode.
Version-Release number of selected component (if applicable):
openssl-1.1.1g-12.el8_3.x86_64
How reproducible:
Always.
Steps to Reproduce:
#include <stdio.h>
#include <openssl/ssl.h>
#include <openssl/fips.h>
#include <openssl/err.h>
int main(int argc, char *argv[])
{
fprintf(stderr,"Startup\n");
fprintf(stderr,"all algos added\n");
if(FIPS_mode())
fprintf(stderr,"FIPS mode already set.\n");
else {
fprintf(stderr,"Not to set FIPS mode...\n");
}
fprintf(stderr,"Attempt FIPS self tests...\n");
if (FIPS_selftest()) {
fprintf(stderr,"FIPS self tests succeeded.\n");
}
else {
fprintf(stderr,"ERROR: FIPS self tests failed.\n");
ERR_print_errors_fp(stderr);
}
return 0;
}
Actual results:
Startup
all algos added
FIPS mode already set.
Attempt FIPS self tests...
ERROR: FIPS self tests failed.
139731764220864:error:0607B0C8:digital envelope routines:EVP_CipherInit_ex:disabled for FIPS:crypto/evp/evp_enc.c:226:
139731764220864:error:2D06F065:FIPS routines:func(111):reason(101):crypto/fips/fips_des_selftest.c:129:
Expected results:
self tests should succeed.
Additional info:
The failure seems to stem from the presence of the the 2-Key 3DES test in FIPS_selftest_des().
From the flags in crypto/evp/e_des3.c that particular cipher is not marked as FIPS.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
