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-2024-28834)
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. (CVE-2024-28835)");
