medium Nessus Plugin ID 81815
Language:
New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Synopsis
The remote host is affected by multiple vulnerabilities.Description
The remote host has a version of McAfee Firewall Enterprise installed that is affected by multiple vulnerabilities in the OpenSSL library :- 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 a remote attacker to defeat cryptographic protection mechanisms. (CVE-2014-3570)
- A NULL pointer dereference flaw exists with dtls1_get_record() when handling DTLS messages. A remote attacker, using a specially crafted DTLS message, can cause a denial of service. (CVE-2014-3571)
- 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)
- A memory leak occurs in dtls1_buffer_record() when handling a saturation of DTLS records containing the same number sequence but for the next epoch. This allows a remote attacker to cause a denial of service.
(CVE-2015-0206)
