    openjdk-7 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in OpenJDK 7.
    
    Software Description:
    - openjdk-7: Open Source Java implementation
    
    Details:
    
    It was discovered that the Security component of OpenJDK did not properly
    ensure that manifest elements were signed before use. An attacker could
    possibly use this to specially construct an untrusted Java application or
    applet that could escape sandbox restrictions. (CVE-2018-3136)
    
    Artem Smotrakov discovered that the HTTP client redirection handler
    implementation in OpenJDK did not clear potentially sensitive information
    in HTTP headers when following redirections to different hosts. An attacker
    could use this to expose sensitive information. (CVE-2018-3139)
    
    It was discovered that the Java Naming and Directory Interface (JNDI)
    implementation in OpenJDK did not properly enforce restrictions specified
    by system properties in some situations. An attacker could potentially use
    this to execute arbitrary code. (CVE-2018-3149)
    
    It was discovered that the Hotspot component of OpenJDK did not properly
    perform access checks in certain cases when performing field link
    resolution. An attacker could use this to specially construct an untrusted
    Java application or applet that could escape sandbox restrictions.
    (CVE-2018-3169)
    
    Felix Dörre discovered that the Java Secure Socket Extension (JSSE)
    implementation in OpenJDK did not ensure that the same endpoint
    identification algorithm was used during TLS session resumption as during
    initial session setup. An attacker could use this to expose sensitive
    information. (CVE-2018-3180)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      icedtea-7-jre-jamvm             7u181-2.6.14-0ubuntu0.3
      openjdk-7-jdk                   7u181-2.6.14-0ubuntu0.3
      openjdk-7-jre                   7u181-2.6.14-0ubuntu0.3
      openjdk-7-jre-headless          7u181-2.6.14-0ubuntu0.3
      openjdk-7-jre-lib               7u181-2.6.14-0ubuntu0.3
    
    This update uses a new upstream release, which includes additional bug
    fixes. After a standard system update you need to restart any Java
    applications or applets to make all the necessary changes.
