Doc Text Cause: Openssl refuses to validate SHA-1 based RSA signature in the DEFAULT crypto policy.

Consequence: When Unbound tries to validate such signature, the error from openssl causes resolution to fail.

Fix: Unbound disables validation support of all RSASHA1 and NSEC3RSASHA1 signatures.

Result: It makes the result insecure under all crypto-policies, but resolves the query successfully.

.Both `bind` and `unbound` disable validation of SHA-1-based signatures

The `bind` and `unbound` components disable validation support of all RSA/SHA1 (algorithm number 5) and RSASHA1-NSEC3-SHA1 (algorithm number 7) signatures, and the SHA-1 usage for signatures is restricted in the DEFAULT system-wide cryptographic policy.

As a result, certain DNSSEC records signed with the SHA-1, RSA/SHA1, and RSASHA1-NSEC3-SHA1 digest algorithms fail to verify in Red Hat Enterprise Linux 9 and the affected domain names become vulnerable.

To work around this problem, upgrade to a different signature algorithm, such as RSA/SHA-256 or elliptic curve keys.

For more information and a list of top-level domains that are affected and vulnerable, see the link:https://access.redhat.com/solutions/6955455/[DNSSEC records signed with RSASHA1 fail to verify] solution.
