    - Resolves: rhbz#1438751

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.

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 6 Update 151, 7 Update 141, or 8 Update 131. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the Networking     subcomponent that allows an unauthenticated, remote     attacker to impact confidentiality and integrity.
    (CVE-2017-3509)

  - An unspecified flaw exists in the JCE subcomponent that     allows a local attacker to gain elevated privileges.
    This vulnerability does not affect Java SE version 6.
    (CVE-2017-3511)

  - An unspecified flaw exists in the AWT subcomponent     that allows an unauthenticated, remote attacker to     execute arbitrary code. This vulnerability does not     affect Java SE version 6. (CVE-2017-3512)

  - An unspecified flaw exists in the AWT subcomponent     that allows an unauthenticated, remote attacker to     execute arbitrary code. (CVE-2017-3514)

  - An unspecified flaw exists in the JAXP subcomponent that     allows an unauthenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3526)

  - Multiple unspecified flaws exist in the Networking     subcomponent that allow an unauthenticated, remote     attacker to gain update, insert, or delete access to     unauthorized data. (CVE-2017-3533, CVE-2017-3544)

  - An unspecified flaw exists in the Security subcomponent     that allows an unauthenticated, remote attacker to gain     update, insert, or delete access to unauthorized data.
    (CVE-2017-3539)

An update for java-1.7.0-oracle is now available for Oracle Java for Red Hat Enterprise Linux 6 and Oracle Java for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Oracle Java SE version 7 includes the Oracle Java Runtime Environment and the Oracle Java Software Development Kit.

This update upgrades Oracle Java SE 7 to version 7 Update 141.

Security Fix(es) :

* This update fixes multiple vulnerabilities in the Oracle Java Runtime Environment and the Oracle Java Software Development Kit.
Further information about these flaws can be found on the Oracle Java SE Critical Patch Update Advisory page, listed in the References section. (CVE-2017-3509, CVE-2017-3511, CVE-2017-3526, CVE-2017-3533, CVE-2017-3539, CVE-2017-3544)

According to the versions of the java-1.7.0-openjdk packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An untrusted library search path flaw was found in the     JCE component of OpenJDK. A local attacker could     possibly use this flaw to cause a Java application     using JCE to load an attacker-controlled library and     hence escalate their privileges. (CVE-2017-3511)

  - It was found that the JAXP component of OpenJDK failed     to correctly enforce parse tree size limits when     parsing XML document. An attacker able to make a Java     application parse a specially crafted XML document     could use this flaw to make it consume an excessive     amount of CPU and memory. (CVE-2017-3526)

  - It was discovered that the HTTP client implementation     in the Networking component of OpenJDK could cache and     re-use an NTLM authenticated connection in a different     security context. A remote attacker could possibly use     this flaw to make a Java application perform HTTP     requests authenticated with credentials of a different     user. (CVE-2017-3509)

  - It was discovered that the Security component of     OpenJDK did not allow users to restrict the set of     algorithms allowed for Jar integrity verification. This     flaw could allow an attacker to modify content of the     Jar file that used weak signing key or hash algorithm.
    (CVE-2017-3539)

  - Newline injection flaws were discovered in FTP and SMTP     client implementations in the Networking component in     OpenJDK. A remote attacker could possibly use these     flaws to manipulate FTP or SMTP connections established     by a Java application. (CVE-2017-3533, CVE-2017-3544)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update for java-1.8.0-openjdk is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.

Security Fix(es) :

* An untrusted library search path flaw was found in the JCE component of OpenJDK. A local attacker could possibly use this flaw to cause a Java application using JCE to load an attacker-controlled library and hence escalate their privileges. (CVE-2017-3511)

* It was found that the JAXP component of OpenJDK failed to correctly enforce parse tree size limits when parsing XML document. An attacker able to make a Java application parse a specially crafted XML document could use this flaw to make it consume an excessive amount of CPU and memory. (CVE-2017-3526)

* It was discovered that the HTTP client implementation in the Networking component of OpenJDK could cache and re-use an NTLM authenticated connection in a different security context. A remote attacker could possibly use this flaw to make a Java application perform HTTP requests authenticated with credentials of a different user. (CVE-2017-3509)

Note: This update adds support for the 'jdk.ntlm.cache' system property which, when set to false, prevents caching of NTLM connections and authentications and hence prevents this issue.
However, caching remains enabled by default.

* It was discovered that the Security component of OpenJDK did not allow users to restrict the set of algorithms allowed for Jar integrity verification. This flaw could allow an attacker to modify content of the Jar file that used weak signing key or hash algorithm.
(CVE-2017-3539)

Note: This updates extends the fix for CVE-2016-5542 released as part of the RHSA-2016:2079 erratum to no longer allow the MD5 hash algorithm during the Jar integrity verification by adding it to the jdk.jar.disabledAlgorithms security property.

* Newline injection flaws were discovered in FTP and SMTP client implementations in the Networking component in OpenJDK. A remote attacker could possibly use these flaws to manipulate FTP or SMTP connections established by a Java application. (CVE-2017-3533, CVE-2017-3544)

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.

Bug Fix(es) :

* When a method is called using the Java Debug Wire Protocol (JDWP) 'invokeMethod' command in a target Java virtual machine, JDWP creates global references for every Object that is implied in the method invocation, as well as for the returned argument of the reference type. Previously, the global references created for such arguments were not collected (deallocated) by the garbage collector after 'invokeMethod' finished. This consequently caused memory leaks, and because references to such objects were never released, the debugged application could be terminated with an Out of Memory error. This bug has been fixed, and the described problem no longer occurs.
