3. Description:
The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime
Environment and the OpenJDK 7 Java Software Development Kit.
Security Fix(es):
* Multiple flaws were discovered in the Serialization and Hotspot
components in OpenJDK. An untrusted Java application or applet could use
these flaws to completely bypass Java sandbox restrictions. (CVE-2016-0686,
CVE-2016-0687)
* It was discovered that the RMI server implementation in the JMX component
in OpenJDK did not restrict which classes can be deserialized when
deserializing authentication credentials. A remote, unauthenticated
attacker able to connect to a JMX port could possibly use this flaw to
trigger deserialization flaws. (CVE-2016-3427)
* It was discovered that the JAXP component in OpenJDK failed to properly
handle Unicode surrogate pairs used as part of the XML attribute values.
Specially crafted XML input could cause a Java application to use an
excessive amount of memory when parsed. (CVE-2016-3425)
* It was discovered that the Security component in OpenJDK failed to check
the digest algorithm strength when generating DSA signatures. The use of a
digest weaker than the key strength could lead to the generation of
signatures that were weaker than expected. (CVE-2016-0695)
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.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
All running instances of OpenJDK Java must be restarted for this update to
take effect.
5. Bugs fixed (https://bugzilla.redhat.com/):
