The DROWN (Decrypting RSA with Obsolete and Weakened eNcryption) attack is a cross-protocol security bug that attacks servers supporting modern SSLv3/TLS protocol suites by using their support for the obsolete, insecure, SSL v2 protocol to leverage an attack on connections using up-to-date protocols that would otherwise be secure.
It resulted from improper input validation (due to a missing bounds check) in the implementation of the TLS heartbeat extension. [5] Thus, the bug's name derived from heartbeat. [6] The vulnerability was classified as a buffer over-read, [7] a situation where more data can be read than should be allowed. [8]

The CCS Injection Vulnerability (CVE-2014-0224) is a security bypass vulnerability that results from a weakness in OpenSSL methods used for keying material. [80] This vulnerability can be exploited through the use of a man-in-the-middle attack, [81] where an attacker may be able to decrypt and modify traffic in transit. A remote unauthenticated ...
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].
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.
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.
