The remote Redhat Enterprise Linux 5 / 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0269 advisory.

    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):

    * It was discovered that the RMI registry and DCG implementations in the RMI component of OpenJDK     performed deserialization of untrusted inputs. A remote attacker could possibly use this flaw to execute     arbitrary code with the privileges of RMI registry or a Java RMI application. (CVE-2017-3241)

    This issue was addressed by introducing whitelists of classes that can be deserialized by RMI registry or     DCG. These whitelists can be customized using the newly introduced sun.rmi.registry.registryFilter and     sun.rmi.transport.dgcFilter security properties.

    * Multiple flaws were discovered in the Libraries and Hotspot components in OpenJDK. An untrusted Java     application or applet could use these flaws to completely bypass Java sandbox restrictions.
    (CVE-2017-3272, CVE-2017-3289)

    * A covert timing channel flaw was found in the DSA implementation in the Libraries component of OpenJDK.
    A remote attacker could possibly use this flaw to extract certain information about the used key via a     timing side channel. (CVE-2016-5548)

    * It was discovered that the Libraries component of OpenJDK accepted ECSDA signatures using non-canonical     DER encoding. This could cause a Java application to accept signature in an incorrect format not accepted     by other cryptographic tools. (CVE-2016-5546)

    * It was discovered that the 2D component of OpenJDK performed parsing of iTXt and zTXt PNG image chunks     even when configured to ignore metadata. An attacker able to make a Java application parse a specially     crafted PNG image could cause the application to consume an excessive amount of memory. (CVE-2017-3253)

    * It was discovered that the Libraries component of OpenJDK did not validate the length of the object     identifier read from the DER input before allocating memory to store the OID. An attacker able to make a     Java application decode a specially crafted DER input could cause the application to consume an excessive     amount of memory. (CVE-2016-5547)

    * It was discovered that the JAAS component of OpenJDK did not use the correct way to extract user DN from     the result of the user search LDAP query. A specially crafted user LDAP entry could cause the application     to use an incorrect DN. (CVE-2017-3252)

    * It was discovered that the Networking component of OpenJDK failed to properly parse user info from the     URL. A remote attacker could cause a Java application to incorrectly parse an attacker supplied URL and     interpret it differently from other applications processing the same URL. (CVE-2016-5552)

    * Multiple flaws were found in the Networking components in OpenJDK. An untrusted Java application or     applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2017-3261, CVE-2017-3231)

    * A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-     middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted     traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite.
    (CVE-2016-2183)

    This update mitigates the CVE-2016-2183 issue by adding 3DES cipher suites to the list of legacy     algorithms (defined using the jdk.tls.legacyAlgorithms security property) so they are only used if     connecting TLS/SSL client and server do not share any other non-legacy cipher suite.

An update for java-1.7.0-openjdk is now available for Red Hat Enterprise Linux 5, 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 Critical. 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) :

* It was discovered that the RMI registry and DCG implementations in the RMI component of OpenJDK performed deserialization of untrusted inputs. A remote attacker could possibly use this flaw to execute arbitrary code with the privileges of RMI registry or a Java RMI application. (CVE-2017-3241)

This issue was addressed by introducing whitelists of classes that can be deserialized by RMI registry or DCG. These whitelists can be customized using the newly introduced sun.rmi.registry.registryFilter and sun.rmi.transport.dgcFilter security properties.

* Multiple flaws were discovered in the Libraries and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions.
(CVE-2017-3272, CVE-2017-3289)

* A covert timing channel flaw was found in the DSA implementation in the Libraries component of OpenJDK. A remote attacker could possibly use this flaw to extract certain information about the used key via a timing side channel. (CVE-2016-5548)

* It was discovered that the Libraries component of OpenJDK accepted ECSDA signatures using non-canonical DER encoding. This could cause a Java application to accept signature in an incorrect format not accepted by other cryptographic tools. (CVE-2016-5546)

* It was discovered that the 2D component of OpenJDK performed parsing of iTXt and zTXt PNG image chunks even when configured to ignore metadata. An attacker able to make a Java application parse a specially crafted PNG image could cause the application to consume an excessive amount of memory. (CVE-2017-3253)

* It was discovered that the Libraries component of OpenJDK did not validate the length of the object identifier read from the DER input before allocating memory to store the OID. An attacker able to make a Java application decode a specially crafted DER input could cause the application to consume an excessive amount of memory. (CVE-2016-5547)

* It was discovered that the JAAS component of OpenJDK did not use the correct way to extract user DN from the result of the user search LDAP query. A specially crafted user LDAP entry could cause the application to use an incorrect DN. (CVE-2017-3252)

* It was discovered that the Networking component of OpenJDK failed to properly parse user info from the URL. A remote attacker could cause a Java application to incorrectly parse an attacker supplied URL and interpret it differently from other applications processing the same URL. (CVE-2016-5552)

* Multiple flaws were found in the Networking components in OpenJDK.
An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2017-3261, CVE-2017-3231)

* A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183)

This update mitigates the CVE-2016-2183 issue by adding 3DES cipher suites to the list of legacy algorithms (defined using the jdk.tls.legacyAlgorithms security property) so they are only used if connecting TLS/SSL client and server do not share any other non-legacy cipher suite.

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Security Fix(es) :

  - It was discovered that the RMI registry and DCG     implementations in the RMI component of OpenJDK     performed deserialization of untrusted inputs. A remote     attacker could possibly use this flaw to execute     arbitrary code with the privileges of RMI registry or a     Java RMI application. (CVE-2017-3241)

This issue was addressed by introducing whitelists of classes that can be deserialized by RMI registry or DCG. These whitelists can be customized using the newly introduced sun.rmi.registry.registryFilter and sun.rmi.transport.dgcFilter security properties.

  - Multiple flaws were discovered in the Libraries and     Hotspot components in OpenJDK. An untrusted Java     application or applet could use these flaws to     completely bypass Java sandbox restrictions.
    (CVE-2017-3272, CVE-2017-3289)

  - A covert timing channel flaw was found in the DSA     implementation in the Libraries component of OpenJDK. A     remote attacker could possibly use this flaw to extract     certain information about the used key via a timing side     channel. (CVE-2016-5548)

  - It was discovered that the Libraries component of     OpenJDK accepted ECSDA signatures using non-canonical     DER encoding. This could cause a Java application to     accept signature in an incorrect format not accepted by     other cryptographic tools. (CVE-2016-5546)

  - It was discovered that the 2D component of OpenJDK     performed parsing of iTXt and zTXt PNG image chunks even     when configured to ignore metadata. An attacker able to     make a Java application parse a specially crafted PNG     image could cause the application to consume an     excessive amount of memory. (CVE-2017-3253)

  - It was discovered that the Libraries component of     OpenJDK did not validate the length of the object     identifier read from the DER input before allocating     memory to store the OID. An attacker able to make a Java     application decode a specially crafted DER input could     cause the application to consume an excessive amount of     memory. (CVE-2016-5547)

  - It was discovered that the JAAS component of OpenJDK did     not use the correct way to extract user DN from the     result of the user search LDAP query. A specially     crafted user LDAP entry could cause the application to     use an incorrect DN. (CVE-2017-3252)

  - It was discovered that the Networking component of     OpenJDK failed to properly parse user info from the URL.
    A remote attacker could cause a Java application to     incorrectly parse an attacker supplied URL and interpret     it differently from other applications processing the     same URL. (CVE-2016-5552)

  - Multiple flaws were found in the Networking components     in OpenJDK. An untrusted Java application or applet     could use these flaws to bypass certain Java sandbox     restrictions. (CVE-2017-3261, CVE-2017-3231)
