    Ubuntu Security Notice USN-3804-1
    October 30, 2018
    
    openjdk-8, openjdk-lts vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in OpenJDK.
    
    Software Description:
    - openjdk-lts: Open Source Java implementation
    - openjdk-8: 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 Utility component of OpenJDK did not properly
    ensure all attributes in a JAR were signed before use. An attacker could
    use this to specially construct an untrusted Java application or applet
    that could escape sandbox restrictions. This issue only affected Ubuntu
    18.04 LTS and Ubuntu 18.10. (CVE-2018-3150)
    
    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)
    
    Krzysztof Szafra?ski discovered that the Scripting component did not
    properly restrict access to the scripting engine in some situations. An
    attacker could use this to specially construct an untrusted Java
    application or applet that could escape sandbox restrictions.
    (CVE-2018-3183)
    
    Tobias Ospelt discovered that the Resource Interchange File Format (RIFF)
    reader implementation in OpenJDK contained an infinite loop. An attacker
    could use this to cause a denial of service. This issue only affected
    Ubuntu 16.04 LTS. (CVE-2018-3214)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.10:
      openjdk-11-jdk                  11.0.1+13-2ubuntu1
      openjdk-11-jre                  11.0.1+13-2ubuntu1
      openjdk-11-jre-headless         11.0.1+13-2ubuntu1
    
    Ubuntu 18.04 LTS:
      openjdk-11-jdk                  10.0.2+13-1ubuntu0.18.04.3
      openjdk-11-jre                  10.0.2+13-1ubuntu0.18.04.3
      openjdk-11-jre-headless         10.0.2+13-1ubuntu0.18.04.3
    
    Ubuntu 16.04 LTS:
      openjdk-8-jdk                   8u181-b13-1ubuntu0.16.04.1
      openjdk-8-jre                   8u181-b13-1ubuntu0.16.04.1
      openjdk-8-jre-headless          8u181-b13-1ubuntu0.16.04.1
      openjdk-8-jre-jamvm             8u181-b13-1ubuntu0.16.04.1
    
    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.
