Security Fix(es) :

  - Multiple flaws were discovered in the RMI and Hotspot     components in OpenJDK. An untrusted Java application or     applet could use these flaws to completely bypass Java     sandbox restrictions. (CVE-2017-10285, CVE-2017-10346)

  - It was discovered that the Kerberos client     implementation in the Libraries component of OpenJDK     used the sname field from the plain text part rather     than encrypted part of the KDC reply message. A     man-in-the- middle attacker could possibly use this flaw     to impersonate Kerberos services to Java applications     acting as Kerberos clients. (CVE-2017-10388)

  - It was discovered that the Security component of OpenJDK     generated weak password-based encryption keys used to     protect private keys stored in key stores. This made it     easier to perform password guessing attacks to decrypt     stored keys if an attacker could gain access to a key     store. (CVE-2017-10356)

  - A flaw was found in the Smart Card IO component in     OpenJDK. An untrusted Java application or applet could     use this flaw to bypass certain Java sandbox     restrictions. (CVE-2017-10274)

  - It was found that the FtpClient implementation in the     Networking component of OpenJDK did not set connect and     read timeouts by default. A malicious FTP server or a     man-in-the-middle attacker could use this flaw to block     execution of a Java application connecting to an FTP     server. (CVE-2017-10355)

  - It was found that the HttpURLConnection and     HttpsURLConnection classes in the Networking component     of OpenJDK failed to check for newline characters     embedded in URLs. An attacker able to make a Java     application perform an HTTP request using an attacker     provided URL could possibly inject additional headers     into the request. (CVE-2017-10295)

  - It was discovered that multiple classes in the JAXP,     Serialization, Libraries, and JAX-WS components of     OpenJDK did not limit the amount of memory allocated     when creating object instances from the serialized form.
    A specially crafted input could cause a Java application     to use an excessive amount of memory when deserialized.
    (CVE-2017-10349, CVE-2017-10357, CVE-2017-10347,     CVE-2017-10281, CVE-2017-10345, CVE-2017-10348,     CVE-2017-10350)

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
