A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing.
Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate
data can take excessive time, leading to increased resource consumption.
This flaw allows a remote attacker to send a specially crafted certificate, causing
GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.

A flaw has been discovered in GnuTLS where an application crash can be induced
when attempting to verify a specially crafted .pem bundle using the
"certtool --verify-chain" command.

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability
that exploits deterministic behavior in systems like GnuTLS, leading to
side-channel leaks. In specific scenarios, such as when using the
GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in
nonce size from 513 to 512 bits, exposing a potential timing side-channel.

CVE-2024-0553
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.
CVE-2024-0567
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack.

Remove branching that depends on secret data.
since the `ok` variable isn't used any more, we can remove all code
used to calculate it
