The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 8 Update 51, 7 Update 85, or 6 Update 101. It is, therefore, affected by security vulnerabilities in the following components :

  - 2D
  - CORBA
  - Deployment
  - Hotspot
  - Install
  - JCE
  - JMX
  - JNDI
  - JSSE
  - Libraries
  - RMI
  - Security

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)

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)

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 to decrypt all traffic.
(CVE-2015-4000)

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)

All running instances of OpenJDK Java must be restarted for the update to take effect.

  - OpenJDK: incorrect OCSP nextUpdate checking (Libraries, 8075374) (CVE-2015-4748)

  - OpenJDK: DnsClient fails to release request information after error (JNDI, 8075378) (CVE-2015-4749)

  - ICU: missing boundary checks in layout engine (OpenJDK 2D, 8071715) (CVE-2015-4760)

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

The version of Java SDK installed on the remote AIX host is affected by multiple vulnerabilities :

  - Java Security Components store plaintext data in memory     dumps, which allows a local attacker to gain access to     sensitive information. (CVE-2015-1931)

  - A flaw exists in the readSerialData() function in     class ObjectInputStream.java when handling OIS data,     which allows an attacker to execute arbitrary code.
    (CVE-2015-2590)

  - Multiple flaws exist in the JCE component due to     various cryptographic operations using non-constant     time comparisons. A remote attacker can exploit this     to conduct timing attacks to gain access to sensitive     information. (CVE-2015-2601)

  - A flaw exists in the ECDH_Derive() function in file     ec.c due to missing EC parameter validation when     performing ECDH key derivation. A remote attacker can     exploit this to access sensitive information.
    (CVE-2015-2613)

  - An unspecified vulnerability exists in the 2D component     that allows a remote attacker to access sensitive     information. (CVE-2015-2619, CVE-2015-2637)

  - A flaw exists in the RMIConnectionImpl constructor     in class RMIConnectionImpl.java due to improper     permission checks when creating repository class     loaders. An attacker can exploit this to bypass sandbox     restrictions and access sensitive information.
    (CVE-2015-2621)

  - A flaw exists in the invoke() method in the class     RemoteObjectInvocationHandler.java due to calls to the     finalize() method being permitted. An attacker can     exploit this to bypass sandbox protections and execute     arbitrary code. (CVE-2015-4733)

  - An unspecified flaw exists in the Deployment component     that allows a local attacker to execute arbitrary code.
    (CVE-2015-4736)

  - A flaw exists in the Security component when handling     Online Certificate Status Protocol (OCSP) responses with     no 'nextUpdate'. A remote attacker can exploit this to     cause an application to accept a revoked X.509     certificate. (CVE-2015-4748)

  - An flaw exists in the query() method in class     DnsClient.java due to a failure by the JNDI component's     exception handling to release request information. A     remote attacker can exploit this to cause a denial of     service. (CVE-2015-4749)

  - An integer overflow condition exists in the layout     engine in the International Components for Unicode for     C/C++ (ICU4C). An attacker, using a specially crafted     font, can exploit this to crash an application using     this library or execute arbitrary code. (CVE-2015-4760)
