    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 JPEGImageReader class in OpenJDK would
    incorrectly read unused image data. An attacker could use this to specially
    construct a jpeg image file that when opened by a Java application would
    cause a denial of service. (CVE-2017-10053)
    
    It was discovered that the JAR verifier in OpenJDK did not properly handle
    archives containing files missing digests. An attacker could use this to
    modify the signed contents of a JAR file. (CVE-2017-10067)
    
    It was discovered that integer overflows existed in the Hotspot component
    of OpenJDK when generating range check loop predicates. An attacker could
    use this to specially construct an untrusted Java application or applet
    that could escape sandbox restrictions and cause a denial of service or
    possibly execute arbitrary code. (CVE-2017-10074)
    
    It was discovered that OpenJDK did not properly process parentheses in
    function signatures. An attacker could use this to specially construct an
    untrusted Java application or applet that could escape sandbox
    restrictions. (CVE-2017-10081)
    
    It was discovered that the ThreadPoolExecutor class in OpenJDK did not
    properly perform access control checks when cleaning up threads. An
    attacker could use this to specially construct an untrusted Java
    application or applet that could escape sandbox restrictions and possibly
    execute arbitrary code. (CVE-2017-10087)
    
    It was discovered that the ServiceRegistry implementation in OpenJDK did
    not perform access control checks in certain situations. An attacker could
    use this to specially construct an untrusted Java application or applet
    that escaped sandbox restrictions. (CVE-2017-10089)
    
    It was discovered that the channel groups implementation in OpenJDK did not
    properly perform access control checks in some situations. An attacker
    could use this to specially construct an untrusted Java application or
    applet that could escape sandbox restrictions. (CVE-2017-10090)
    
    It was discovered that the DTM exception handling code in the JAXP
    component of OpenJDK did not properly perform access control checks. An
    attacker could use this to specially construct an untrusted Java
    application or applet that could escape sandbox restrictions.
    (CVE-2017-10096)
    
    It was discovered that the JAXP component of OpenJDK incorrectly granted
    access to some internal resolvers. An attacker could use this to specially
    construct an untrusted Java application or applet that could escape sandbox
    restrictions. (CVE-2017-10101)
    
    It was discovered that the Distributed Garbage Collector (DGC) in OpenJDK
    did not properly track references in some situations. A remote attacker
    could possibly use this to execute arbitrary code. (CVE-2017-10102)
    
    It was discovered that the Activation ID implementation in the RMI
    component of OpenJDK did not properly check access control permissions in
    some situations. An attacker could use this to specially construct an
    untrusted Java application or applet that could escape sandbox
    restrictions. (CVE-2017-10107)
    
    It was discovered that the BasicAttribute class in OpenJDK did not properly
    bound memory allocation when de-serializing objects. An attacker could use
    this to cause a denial of service (memory consumption). (CVE-2017-10108)
    
    It was discovered that the CodeSource class in OpenJDK did not properly
    bound memory allocations when de-serializing object instances. An attacker
    could use this to cause a denial of service (memory consumption).
    (CVE-2017-10109)
    
    It was discovered that the AWT ImageWatched class in OpenJDK did not
    properly perform access control checks, An attacker could use this to
    specially construct an untrusted Java application or applet that could
    escape sandbox restrictions (CVE-2017-10110)
    
    It was discovered that a timing side-channel vulnerability existed in the
    DSA implementation in OpenJDK. An attacker could use this to expose
    sensitive information. (CVE-2017-10115)
    
    It was discovered that the LDAP implementation in OpenJDK incorrectly
    followed references to non-LDAP URLs. An attacker could use this to
    specially craft an LDAP referral URL that exposes sensitive information or
    bypass access restrictions. (CVE-2017-10116)
    
    It was discovered that a timing side-channel vulnerability existed in the
    ECDSA implementation in OpenJDK. An attacker could use this to expose
    sensitive information. (CVE-2017-10118)
    
    Ilya Maykov discovered that a timing side-channel vulnerability existed in
    the PKCS#8 implementation in OpenJDK. An attacker could use this to expose
    sensitive information. (CVE-2017-10135)
    
    It was discovered that the Elliptic Curve (EC) implementation in OpenJDK
    did not properly compute certain elliptic curve points. An attacker could
    use this to expose sensitive information. (CVE-2017-10176)
    
    It was discovered that OpenJDK did not properly perform access control
    checks when handling Web Service Definition Language (WSDL) XML documents.
    An attacker could use this to expose sensitive information.
    (CVE-2017-10243)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      icedtea-7-jre-jamvm             7u151-2.6.11-0ubuntu1.14.04.1
      openjdk-7-jre                   7u151-2.6.11-0ubuntu1.14.04.1
      openjdk-7-jre-headless          7u151-2.6.11-0ubuntu1.14.04.1
      openjdk-7-jre-lib               7u151-2.6.11-0ubuntu1.14.04.1
      openjdk-7-jre-zero              7u151-2.6.11-0ubuntu1.14.04.1
    
    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.
