Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions.
(CVE-2015-4760 , CVE-2015-2628 , CVE-2015-4731 , CVE-2015-2590 , CVE-2015-4732 , CVE-2015-4733)

A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748)

It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601)

It was discovered that the GCM (Galois Counter Mode) implementation in the Security component of OpenJDK failed to properly perform a null check. This could cause the Java Virtual Machine to crash when an application performed encryption using a block cipher in the GCM mode.
(CVE-2015-2659)

A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808)

Please note that with this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue.

A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic.
(CVE-2015-4000)

Please note that this update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749)

Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
(CVE-2015-2621 , CVE-2015-2632)

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 address resolves rather than for the IP address.
(CVE-2015-2625)

Multiple insecure temporary file use issues were found in the way the Hotspot component in OpenJDK created performance statistics and error log files. A local attacker could possibly make a victim using OpenJDK overwrite arbitrary files using a symlink attack.

According to its self-reported version number, the version of Junos Space running on the remote device is prior to 15.1R2. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists in the JCE component in the Oracle Java     runtime due to various cryptographic operations using     non-constant time comparisons. An unauthenticated,     remote attacker can exploit this, via timing attacks,     to disclose potentially sensitive information.
    (CVE-2015-2601)

  - A flaw exists in the JCE component in the Oracle Java     runtime, within the ECDH_Derive() function, due to     missing EC parameter validation when performing ECDH key     derivation. A remote attacker can exploit this to     disclose potentially sensitive information.
    (CVE-2015-2613)

  - A flaw exists in the JSSE component in the Oracle Java     runtime, related to performing X.509 certificate identity     checks, that allows a remote attacker to disclose     potentially sensitive information. (CVE-2015-2625)

  - A NULL pointer dereference flaw exists in the Security     component in the Oracle Java runtime, which is related     to the GCM (Galois Counter Mode) implementation when     performing encryption using a block cipher in GCM mode.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2015-2659)

  - A security feature bypass vulnerability exists, known as     Bar Mitzvah, due to improper combination of state data     with key data by the RC4 cipher algorithm during the     initialization phase. A man-in-the-middle attacker can     exploit this, via a brute-force attack using LSB values,     to decrypt the traffic. (CVE-2015-2808)

  - A man-in-the-middle vulnerability, known as Logjam,     exists due to a flaw in the SSL/TLS protocol. A remote     attacker can exploit this flaw to downgrade connections     using ephemeral Diffie-Hellman key exchange to 512-bit     export-grade cryptography. (CVE-2015-4000)

  - A flaw exists in the Security component in the Oracle     Java runtime when handling Online Certificate Status     Protocol (OCSP) responses with no 'nextUpdate' date     specified. A remote attacker can exploit this to cause a     revoked X.509 certificate to be accepted.
    (CVE-2015-4748)

  - A flaw exists in the JNDI component in the Oracle Java     runtime, within the DnsClient::query() function, due to     a failure by DnsClient exception handling to release     request information. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition.
