Description Christopher Fore 2024-03-22 20:10:05 UTC 
CVE-2024-28834: 

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-2024-28835:

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.

Depending on the test failure since that'll be a predecessor to a newer stablereq anyway...
