Cisco Small Business RV Router Information Disclosure Vulnerability
The Cisco Small Business RV Series routers provide virtual private network technology remote. Cisco Small Business RV Routers 4.x, SA500 Security Appliance Version 2.2.07 random number generator fails to have effective entropy, which can allow a remote attacker to determine the TLS key pair throu...
TLS NPN Supported Protocol Enumeration
The remote host supports the TLS NPN Transport Layer Security Next Protocol Negotiation extension. This plugin enumerates the protocols the extension supports. TRUSTED...
wireshark: TLS/SSL decryption crash (wnpa-sec-2015-05)
Buffer underflow in the ssldecryptrecord function in epan/dissectors/packet-ssl-utils.c in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 allows remote attackers to cause a denial of service application crash via a crafted packet that is improperly handled during decryption of an SSL...
Microsoft Windows Schannel TLS Three Times Handshake Vulnerability
Microsoft Windows is a family of operating systems released by Microsoft Corporation in the U.S. Microsoft Schannel or Secure Channel is one of the Security Support Providers SSPs that implements the Secure Socket Layer SSL and Transport Layer Security TLS protocols and provides authentication...
The vulnerability of the Mac OS X operating system, which allows a hacker to compromise security of information.
The vulnerability of the TLS protocol implementation in the Mac OS X operating system is related to errors in the key exchange process. Exploiting this vulnerability can allow a malicious actor to compromise information security remotely...

mysql: use of SSL/TLS can not be enforced in mysql client library (oCERT-2015-003, BACKRONYM)
It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the "--ssl" option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client an...
NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)
It was found that NSS permitted skipping of the ServerKeyExchange packet during a handshake involving ECDHE Elliptic Curve Diffie-Hellman key Exchange. A remote attacker could use this flaw to bypass the forward-secrecy of a TLS/SSL connection...

Denial of Service Vulnerability in Multiple EMC RSA Products
EMC RSA BSAFE Micro Edition Suite MES and others are products of EMC Corporation.EMC RSA BSAFE is a security software product that supports cryptographic algorithms, certificate chain validation, and Transport Layer Security TLS encryption suites, among other things, to help users achieve a wide...
The vulnerability of the Cisco Adaptive Security Appliance allows attackers to carry out “man-in-the-middle” attacks.
The vulnerability of the Cisco Adaptive Security Appliance’s TLS implementation is due to problems with the use of cryptography. Exploiting this vulnerability allows a malicious actor to carry out “man-in-the-middle” attacks remotely...
The vulnerability of the OpenSSL library, which allows a hacker to trigger a service failure
The vulnerability of the ssleayrandbytes function in the OpenSSL library is related to buffer overflows in dynamic memory, caused by integer overflows. Exploiting this vulnerability could allow a malicious actor to cause service interruptions by establishing multiple TLS sessions remotely...
LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks
A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...
TLS: MITM attacks via session renegotiation
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services IIS 7.0, modssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services NSS 3.12.4 and earlier, multiple Cis...
SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic...

OpenJDK: name for reverse DNS lookup used in certificate identity check (JSSE, 8067694)
A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP addres...
