An update for java-1.7.0-openjdk is now available for Red Hat Enterprise Linux 6 and 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-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 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-2016:2658 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)

An update for java-1.8.0-openjdk is now available for Red Hat Enterprise Linux 6.

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)

* 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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1119 advisory.

    Oracle Java SE version 6 includes the Oracle Java Runtime Environment and the Oracle Java Software     Development Kit.

    This update upgrades Oracle Java SE 6 to version 6 Update 151.

    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-2017-3526,     CVE-2017-3533, CVE-2017-3539, CVE-2017-3544)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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 Java SE installed on the remote host is prior to 6 Update 151, 7 Update 141, or 8 Update 131, and 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)
