The vulnerability in the implementation of the TLS (Transport Layer Security) protocol for Windows operating systems allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of the TLS Transport Layer Security protocol implementation in Windows operating systems is related to the use of weak hashing algorithms. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain unauthorized access to protected information...

nss: PKCS#1 v1.5 signatures can be used for TLS 1.3

A vulnerability exists where it possible to force Network Security Services NSS to sign CertificateVerify with PKCS1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerabilit...

nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state

A protocol downgrade flaw was found in Network Security Services NSS. After a HelloRetryRequest has been sent, the client may negotiate a lower protocol than TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data...

CVE-2020-5929

In versions 13.0.0-13.0.0 HF2, 12.1.0-12.1.2 HF1, and 11.6.1-11.6.2, BIG-IP platforms with Cavium Nitrox SSL hardware acceleration cards, a Virtual Server configured with a Client SSL profile, and using Anonymous ADH or Ephemeral DHE Diffie-Hellman key exchange and Single DH use option not enable...

systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent)
