    Ubuntu Security Notice USN-3275-2


    15th May, 2017

    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


    USN-3275-1 fixed vulnerabilities in OpenJDK 8. This update provides
    the corresponding updates for OpenJDK 7.

    Original advisory details:

    It was discovered that OpenJDK improperly re-used cached NTLM
    connections in some situations. A remote attacker could possibly
    use this to cause a Java application to perform actions with the
    credentials of a different user. (CVE-2017-3509)

    It was discovered that an untrusted library search path flaw existed
    in the Java Cryptography Extension (JCE) component of OpenJDK. A
    local attacker could possibly use this to gain the privileges of a
    Java application. (CVE-2017-3511)

    It was discovered that the Java API for XML Processing (JAXP) component
    in OpenJDK did not properly enforce size limits when parsing XML
    documents. An attacker could use this to cause a denial of service
    (processor and memory consumption). (CVE-2017-3526)

    It was discovered that the FTP client implementation in OpenJDK did
    not properly sanitize user inputs. If a user was tricked into opening
    a specially crafted FTP URL, a remote attacker could use this to
    manipulate the FTP connection. (CVE-2017-3533)

    It was discovered that OpenJDK allowed MD5 to be used as an algorithm
    for JAR integrity verification. An attacker could possibly use this
    to modify the contents of a JAR file without detection. (CVE-2017-3539)

    It was discovered that the SMTP client implementation in OpenJDK
    did not properly sanitize sender and recipient addresses. A remote
    attacker could use this to specially craft email addresses and gain
    control of a Java application's SMTP connections. (CVE-2017-3544)
