CVE-2016-2183

The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted...

Gratipay: Insecure Transportation Security Protocol Supported (TLS 1.0)

Description: Its observed that that insecure transportation security protocol TLS 1.0 is supported by your web server. TLS 1.0 has several flaws. An attacker can cause connection failures and they can trigger the use of TLS 1.0 to exploit vulnerabilities like BEAST. Websites using TLS 1.0 will be...

SWEET32 attack on Triple-DES

Because DES and triple-DES has only a 64-bit block size, birthday attacks are a real concern. For example, with the ability to run Javascript in a browser, it is possible to send enough traffic to cause a collision, and then use that information to recover something like a session Cookie...

PT-2016-3301

Name of the Vulnerable Software and Affected Versions OpenVPN versions prior to the fixed version Description The issue is related to the use of 64-bit block ciphers in OpenVPN, which can be exploited by remote attackers to obtain cleartext data via a birthday attack, specifically a "Sweet32"...

openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)

It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...

OpenSSL: SSLv2 doesn't block disabled ciphers

A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks...

openssl: assertion failure in SSLv2 servers

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled...

Amazon Linux AMI : openssl (ALAS-2016-661) (DROWN) (SLOTH)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is...
