Splunk Enterprise 6.2.x < 6.2.2 Multiple Vulnerabilities (FREAK)

According to its version number, the Splunk Enterprise hosted on the remote web server is version 6.2.x prior to 6.2.2. It is, therefore, affected by the following vulnerabilities : - A flaw exists with ECDH handshakes when using an ECDSA certificate without a ServerKeyExchange message. This allo...

Vulnerability in OpenSSL - Handshake with unseeded PRNG

Under certain conditions an OpenSSL 1.0.2 client can complete a handshake with an unseeded PRNG. If the handshake succeeds then the client random that has been used will have been generated from a PRNG with insufficient entropy and therefore the output may be predictable. Found by Matt Caswell...

mono -- TLS bugs

The Mono project reports: Mono’s implementation of the SSL/TLS stack failed to check the order of the handshake messages. Which would allow various attacks on the protocol to succeed. Details of this vulnerability are discussed in SKIP-TLS post. Mono’s implementation of SSL/TLS also contained...

RHEL 5 / 6 : Red Hat Satellite IBM Java Runtime (RHSA-2015:0264)

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0264 advisory. This update corrects several security vulnerabilities in the IBM Java Runtime Environment shipped as part of Red Hat Satellite 5.6. In a...

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

It was discovered that the TLS/SSL implementation in the JSSE component in OpenJDK failed to properly verify the server identity during the renegotiation following session resumption, making it possible for malicious TLS/SSL servers to perform a Triple Handshake attack against clients using JSSE...

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...

AIX OpenSSL Advisory : openssl_advisory12.asc (FREAK)

The version of OpenSSL installed on the remote AIX host is affected by the following vulnerabilities : - The BIGNUM squaring BNsqr implementation does not properly calculate the square of a BIGNUM value. This allows remote attackers to defeat cryptographic protection mechanisms. CVE-2014-3570 - A...

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...
