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...

Elasticsearch remote code execution CVE-2015-5377

Summary Elasticsearch versions prior to 1.6.1 are vulnerable to an engineered attack on its transport protocol that enables remote code execution. This issue is related to the Groovy announcement in CVE-2015-3253. Deployments are vulnerable even when Groovy dynamic scripting is disabled. We have...

elasticsearch -- remote code execution via transport protocol

Elastic reports: Vulnerability Summary: Elasticsearch versions prior to 1.6.1 are vulnerable to an attack that can result in remote code execution. Remediation Summary: Users should upgrade to 1.6.1 or 1.7.0. Alternately, ensure that only trusted applications have access to the transport protocol...

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...
