Security Fix(es):

* A flaw was found in the AWT component of OpenJDK. An untrusted Java
application or applet could use this flaw to bypass certain Java sandbox
restrictions. (CVE-2018-2641)

* It was discovered that the LDAPCertStore class in the JNDI component of
OpenJDK failed to securely handle LDAP referrals. An attacker could
possibly use this flaw to make it fetch attacker controlled certificate
data. (CVE-2018-2633)

* The JGSS component of OpenJDK ignores the value of the
javax.security.auth.useSubjectCredsOnly property when using HTTP/SPNEGO
authentication and always uses global credentials. It was discovered that
this could cause global credentials to be unexpectedly used by an
untrusted Java application. (CVE-2018-2634)

* It was discovered that the JMX component of OpenJDK failed to properly
set the deserialization filter for the SingleEntryRegistry in certain
cases. A remote attacker could possibly use this flaw to bypass intended
deserialization restrictions. (CVE-2018-2637)

* It was discovered that the LDAP component of OpenJDK failed to properly
encode special characters in user names when adding them to an LDAP search
query. A remote attacker could possibly use this flaw to manipulate LDAP
queries performed by the LdapLoginModule class. (CVE-2018-2588)

* It was discovered that the DNS client implementation in the JNDI
component of OpenJDK did not use random source ports when sending out DNS
queries. This could make it easier for a remote attacker to spoof
responses to those queries. (CVE-2018-2599)

* It was discovered that the I18n component of OpenJDK could use an
untrusted search path when loading resource bundle classes. A local
attacker could possibly use this flaw to execute arbitrary code as another
local user by making their Java application load an attacker controlled
class file. (CVE-2018-2602)

* It was discovered that the Libraries component of OpenJDK failed to
sufficiently limit the amount of memory allocated when reading DER encoded
input. A remote attacker could possibly use this flaw to make a Java
application use an excessive amount of memory if it parsed attacker
supplied DER encoded input. (CVE-2018-2603)

* It was discovered that the key agreement implementations in the JCE
component of OpenJDK did not guarantee sufficient strength of used keys to
adequately protect generated shared secret. This could make it easier to
break data encryption by attacking key agreement rather than the
encryption using the negotiated secret. (CVE-2018-2618)

* It was discovered that the JGSS component of OpenJDK failed to properly
handle GSS context in the native GSS library wrapper in certain cases. A
remote attacker could possibly make a Java application using JGSS to use a
previously freed context. (CVE-2018-2629)

* It was discovered that multiple classes in the Libraries, AWT, and JNDI
components of OpenJDK did not sufficiently validate input when creating
object instances from the serialized form. A specially-crafted input could
cause a Java application to create objects with an inconsistent state or
use an excessive amount of memory when deserialized. (CVE-2018-2663,
CVE-2018-2677, CVE-2018-2678)

* It was discovered that multiple encryption key classes in the Libraries
component of OpenJDK did not properly synchronize access to their internal
data. This could possibly cause a multi-threaded Java application to apply
weak encryption to data because of the use of a key that was zeroed out.
(CVE-2018-2579)
