Updated ipa packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System CVSS base scores, which give...

SSL/TLS Cryptographic Degradation Man-in-the-Middle Hijacking Vulnerability

SSL/TLS is a cryptographic application. SSL/TLS has a security vulnerability that can lead to an attack known as FREAK Factoring RSA Export Keys, which can be exploited by an attacker to reduce the level of encryption and decrypt communications through a man-in-the-middle attack...

UBUNTU-CVE-2015-0834

The WebRTC subsystem in Mozilla Firefox before 36.0 recognizes turns: and stuns: URIs but accesses the TURN or STUN server without using TLS, which makes it easier for man-in-the-middle attackers to discover credentials by spoofing a server and completing a brute-force attack within a short time...

OpenJDK: incorrect tracking of ChangeCipherSpec during SSL/TLS handshake (JSSE, 8057555)

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

OpenJDK: incorrect tracking of ChangeCipherSpec during SSL/TLS handshake (JSSE, 8057555)

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

openssl: race condition in ssl_parse_serverhello_tlsext

A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execut...

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

OpenJDK: incorrect tracking of ChangeCipherSpec during SSL/TLS handshake (JSSE, 8057555)

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

openssl: TLS protocol downgrade attack

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions...

OpenJDK: incorrect tracking of ChangeCipherSpec during SSL/TLS handshake (JSSE, 8057555)

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption...

Wireshark TLS/SSL Decryption Denial of Service Vulnerability

Wireshark is an open source network protocol analysis tool. A denial of service vulnerability exists in Wireshark TLS/SSL because it fails to properly handle certain types of packets. An attacker could exploit this vulnerability to crash the affected application and deny service to legitimate use...

OpenJDK: Triple Handshake attack against TLS/SSL connections (JSSE, 8037066)
