Juniper NSM < 2012.2R11 Multiple OpenSSL Vulnerabilities (JSA10679) (FREAK)

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote host is running a version of NSM (Network and Security Manager) Server that is prior to 2012.2R11. It is, therefore, affected by multiple vulnerabilities related to OpenSSL :

- A NULL pointer dereference flaw exists when the SSLv3 option isn't enabled and an SSLv3 ClientHello is received. This allows a remote attacker, using an unexpected handshake, to crash the daemon, resulting in a denial of service. (CVE-2014-3569)

- The BIGNUM squaring (BN_sqr) implementation does not properly calculate the square of a BIGNUM value. This allows remote attackers to defeat cryptographic protection mechanisms. (CVE-2014-3570)

- A flaw exists with ECDH handshakes when using an ECDSA certificate without a ServerKeyExchange message. This allows a remote attacker to trigger a loss of forward secrecy from the ciphersuite. (CVE-2014-3572)

- A flaw exists when accepting non-DER variations of certificate signature algorithms and signature encodings due to a lack of enforcement of matches between signed and unsigned portions. A remote attacker, by including crafted data within a certificate's unsigned portion, can bypass fingerprint-based certificate-blacklist protection mechanisms. (CVE-2014-8275)

- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA 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 connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)

- A flaw exists when accepting DH certificates for client authentication without the CertificateVerify message.
This allows a remote attacker to authenticate to the service without a private key. (CVE-2015-0205)

Solution

Upgrade to Juniper NSM version 2012.2R11 or later.
