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.
in php/ext/openssl, default message digest algo is hardcoded to md5, which is now rejected by recent changes in openssl.
So ext/openssl/tests/bug36732.phpt now fails (in recent build).
Proposal, which to sha1 for consistency.
in ext/openssl/openssl.c, in php_openssl_parse_config function:
if (req->md_alg == NULL) {
- req->md_alg = req->digest = EVP_md5();
+ req->md_alg = req->digest = EVP_sha1();
}
The SHA-256 is required by NIST since beginning of this year and it is reasonable requirement given the SHA-1 weaknesses. The default in the openssl default config file is SHA-256. On the other hand OpenSSL library default is SHA-1.
One thing that's needed to be considered is that there are still widely used legacy applications that cannot verify signatures that use SHA-256.
Notice: PHP will use sha256 algo as configured. in provided openssl.cnf
So, only PHP users using a non default config, without default_md, will be affected.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
