Title:RedHat Update for java-1.8.0-openjdk RHSA-2017:2998-01
Summary:The remote host is missing an update for the 'java-1.8.0-openjdk'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'java-1.8.0-openjdk'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The java-1.8.0-openjdk packages provide the
OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.

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,

* 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.

* 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.

* 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.

* 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,

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.
