In 2014, the POODLE vulnerability of SSL 3.0 was discovered, which takes advantage of the known vulnerabilities in CBC, and an insecure fallback negotiation used in browsers. [ 31 ] TLS 1.2 (2008) introduced a means to identify the hash used for digital signatures.
WinSCP (FTP client for Windows) 5.5.2 and some earlier versions (only vulnerable with FTP over TLS/SSL, fixed in 5.5.3) [130] Multiple VMware products, including VMware ESXi 5.5, VMware Player 6.0, VMware Workstation 10 and the series of Horizon products, emulators and cloud computing suites [131] Several other Oracle Corporation applications ...
CRL for a revoked cert of Verisign CA. There are two different states of revocation defined in RFC 5280: Revoked A certificate is irreversibly revoked if, for example, it is discovered that the certificate authority (CA) had improperly issued a certificate, or if a private-key is thought to have been compromised.
Certificate revocation is "an important tool" for dealing with attacks and accidental compromises. RFC 9325 places a normative requirement on TLS implementations to have some means of distrusting certificates. [9]
Although this vulnerability only exists in SSL 3.0 and most clients and servers support TLS 1.0 and above, all major browsers voluntarily downgrade to SSL 3.0 if the handshakes with newer versions of TLS fail unless they provide the option for a user or administrator to disable SSL 3.0 and the user or administrator does so [citation needed].
Windows 10 version 1903 and 1909, and Server Core installations of Windows Server, versions 1903 and 1909 [5] SMBGhost (or SMBleedingGhost or CoronaBlue ) is a type of security vulnerability , with wormlike features, that affects Windows 10 computers and was first reported publicly on 10 March 2020.
The ISRG provides free and open-source reference implementations for ACME: certbot is a Python-based implementation of server certificate management software using the ACME protocol, [6] [7] [8] and boulder is a certificate authority implementation, written in Go.
