    openjdk-8 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.04
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in OpenJDK 8.
    
    Software Description:
    - openjdk-8: 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 the JavaScript Scripting component of OpenJDK
    incorrectly allowed access to Java APIs. An attacker could use this
    to specially craft JavaScript code to bypass access restrictions.
    (CVE-2017-10078)
    
    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)
    
    Jackson Davis discovered that the LambdaFormEditor class in the
    Libraries component of OpenJDK did not correctly perform bounds checks
    in the permuteArgumentsForm() function. 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-2017-10111)
    
    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 restrict weak key
    sizes in some situations. An attacker could use this to specially
    construct an untrusted Java application or applet that could escape
    sandbox restrictions. (CVE-2017-10193)
    
    It was discovered that OpenJDK did not properly enforce disabled
    algorithm restrictions on X.509 certificate chains. An attacker
    could use this to expose sensitive information or escape sandbox
    restrictions. (CVE-2017-10198)
    
    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)
