Several vulnerabilities have been discovered in OpenJDK, an implementation of the Oracle Java platform, resulting in denial of service, unauthorized access, sandbox bypass or HTTP header injection.

For Debian 7 'Wheezy', these problems have been fixed in version 7u171-2.6.13-1~deb7u1.

We recommend that you upgrade your openjdk-7 packages.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2018-2515:01 advisory.

    * Multiple flaws were found in the Hotspot and AWT components of OpenJDK. An untrusted Java application or     applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2018-2582, CVE-2018-2641)
      * It was discovered that the LDAPCertStore class in the JNDI component of OpenJDK failed to securely     handle LDAP referrals. An attacker could possibly use this flaw to make it fetch attacker controlled     certificate data. (CVE-2018-2633)
      * The JGSS component of OpenJDK ignores the value of the javax.security.auth.useSubjectCredsOnly     property when using HTTP/SPNEGO authentication and always uses global credentials. It was discovered that     this could cause global credentials to be unexpectedly used by an untrusted Java application.
    (CVE-2018-2634)
      * It was discovered that the JMX component of OpenJDK failed to properly set the deserialization filter     for the SingleEntryRegistry in certain cases. A remote attacker could possibly use this flaw to bypass     intended deserialization restrictions. (CVE-2018-2637)
      * It was discovered that the LDAP component of OpenJDK failed to properly encode special characters in     user names when adding them to an LDAP search query. A remote attacker could possibly use this flaw to     manipulate LDAP queries performed by the LdapLoginModule class. (CVE-2018-2588)
      * It was discovered that the DNS client implementation in the JNDI component of OpenJDK did not use     random source ports when sending out DNS queries. This could make it easier for a remote attacker to spoof     responses to those queries. (CVE-2018-2599)
      * It was discovered that the I18n component of OpenJDK could use an untrusted search path when loading     resource bundle classes. A local attacker could possibly use this flaw to execute arbitrary code as     another local user by making their Java application load an attacker controlled class file.
    (CVE-2018-2602)
      * It was discovered that the Libraries component of OpenJDK failed to sufficiently limit the amount of     memory allocated when reading DER encoded input. A remote attacker could possibly use this flaw to make a     Java application use an excessive amount of memory if it parsed attacker supplied DER encoded input.
    (CVE-2018-2603)
      * It was discovered that the key agreement implementations in the JCE component of OpenJDK did not     guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make     it easier to break data encryption by attacking key agreement rather than the encryption using the     negotiated secret. (CVE-2018-2618)
      * It was discovered that the JGSS component of OpenJDK failed to properly handle GSS context in the     native GSS library wrapper in certain cases. A remote attacker could possibly make a Java application     using JGSS to use a previously freed context. (CVE-2018-2629)
      * It was discovered that multiple classes in the Libraries, AWT, and JNDI components of OpenJDK did not     sufficiently validate input when creating object instances from the serialized form. A specially-crafted     input could cause a Java application to create objects with an inconsistent state or use an excessive     amount of memory when deserialized. (CVE-2018-2663, CVE-2018-2677, CVE-2018-2678)
      * It was discovered that multiple encryption key classes in the Libraries component of OpenJDK did not     properly synchronize access to their internal data. This could possibly cause a multi-threaded Java     application to apply weak encryption to data because of the use of a key that was zeroed out.
    (CVE-2018-2579)     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.
