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...

openssl: SSLv2 Bleichenbacher protection overwrites wrong bytes for export ciphers

It was discovered that the SSLv2 protocol implementation in OpenSSL did not properly implement the Bleichenbacher protection for export cipher suites. An attacker could use a SSLv2 server using OpenSSL as a Bleichenbacher oracle...

BlackBerry Enterprise Server SSL/TLS EXPORT_RSA Ciphers Downgrade MitM (KB36811) (FREAK)

The version of BlackBerry Enterprise Server on the remote host is affected by a security feature bypass vulnerability, known as FREAK Factoring attack on RSA-EXPORT Keys, due to the support of weak EXPORTRSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may ...

UBUNTU-CVE-2015-2319

The TLS stack in Mono before 3.12.1 makes it easier for remote attackers to conduct cipher-downgrade attacks to EXPORTRSA ciphers via crafted TLS traffic, related to the "FREAK" issue, a different vulnerability than CVE-2015-0204...

Opera < 28.0.1750.40 SSL/TLS EXPORT_RSA Ciphers Downgrade MitM (Mac OS X) (FREAK)

The remote Mac OS X host has a version of the Opera web browser installed that is prior to 28.0.1750.40. It is, therefore, affected by a security feature bypass vulnerability, known as FREAK Factoring attack on RSA-EXPORT Keys, due to the support of weak EXPORTRSA cipher suites with keys less tha...

Dealing with FREAK and SuperFish

Security Dealing with FREAK and SuperFish Share March 10th, 2015 The FREAK TLS attack Following the trend of memorable names for TLS attacks, FREAK was recently announced. This exploits a bug in some TLS libraries, combined with the support of ancient weak ciphers, to enable a MitM to force...

Microsoft Schannel Vulnerable to FREAK

Microsoft today issued an advisory warning Windows users that Secure Channel, or Schannel, the Windows implementation of SSL/TLS, is vulnerable to the FREAK attack. Disclosed this week, FREAK CVE-2015-1637 is the latest big Internet bug. It affects a number of SSL clients, including OpenSSL, and...

MS KB3046015: Vulnerability in Schannel Could Allow Security Feature Bypass (FREAK)

The remote Windows host is affected by a security feature bypass vulnerability, known as FREAK Factoring attack on RSA-EXPORT Keys, due to the support of weak EXPORTRSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS...

SSL/TLS EXPORT_RSA <= 512-bit Cipher Suites Supported (FREAK)

The remote host supports EXPORTRSA cipher suites with keys less than or equal to 512 bits. An attacker can factor a 512-bit RSA modulus in a short amount of time. A man-in-the middle attacker may be able to downgrade the session to use EXPORTRSA cipher suites e.g. CVE-2015-0204. Thus, it is...

OWASP SSL audit: O-Saft

O-Saft is an easy to use tool to show informations about SSL certificate and tests the SSL connection according given list of ciphers and various SSL configurations. It’s designed to be used by penetration testers, security auditors or server administrators. The idea is to show the important...
