"It was discovered that a race condition existed in the cryptography
implementation in OpenJDK. An attacker could possibly use this to
expose sensitive information. (CVE-2018-2579)

It was discovered that the LDAP implementation in OpenJDK did not
properly encode login names. A remote attacker could possibly use this
to expose sensitive information. (CVE-2018-2588)

It was discovered that the DNS client implementation in OpenJDK did
not properly randomize source ports. A remote attacker could use this
to spoof responses to DNS queries made by Java applications.
(CVE-2018-2599)

It was discovered that the Internationalization component of OpenJDK
did not restrict search paths when loading resource bundle classes. A
local attacker could use this to trick a user into running malicious
code. (CVE-2018-2602)

It was discovered that OpenJDK did not properly restrict memory
allocations when parsing DER input. A remote attacker could possibly
use this to cause a denial of service. (CVE-2018-2603)

It was discovered that the Java Cryptography Extension (JCE)
implementation in OpenJDK in some situations did guarantee sufficient
strength of keys during key agreement. An attacker could use this to
expose sensitive information. (CVE-2018-2618)

It was discovered that the Java GSS implementation in OpenJDK in some
situations did not properly handle GSS contexts in the native GSS
library. An attacker could possibly use this to access unauthorized
resources. (CVE-2018-2629)

It was discovered that the LDAP implementation in OpenJDK did not
properly handle LDAP referrals in some situations. An attacker could
possibly use this to expose sensitive information or gain unauthorized
privileges. (CVE-2018-2633)

It was discovered that the Java GSS implementation in OpenJDK in some
situations did not properly apply subject credentials. An attacker
could possibly use this to expose sensitive information or gain access
to unauthorized resources. (CVE-2018-2634)

It was discovered that the Java Management Extensions (JMX) component
of OpenJDK did not properly apply deserialization filters in some
situations. An attacker could use this to bypass deserialization
restrictions. (CVE-2018-2637)

It was discovered that a use-after-free vulnerability existed in the
AWT component of OpenJDK when loading the GTK library. An attacker
could possibly use this to execute arbitrary code and escape Java
sandbox restrictions. (CVE-2018-2641)

It was discovered that in some situations OpenJDK did not properly
validate objects when performing deserialization. An attacker could
use this to cause a denial of service (application crash or excessive
memory consumption). (CVE-2018-2663)

It was discovered that the AWT component of OpenJDK did not properly
restrict the amount of memory allocated when deserializing some
objects. An attacker could use this to cause a denial of service
(excessive memory consumption). (CVE-2018-2677)

It was discovered that the JNDI component of OpenJDK did not properly
restrict the amount of memory allocated when deserializing objects in
some situations. An attacker could use this to cause a denial of
service (excessive memory consumption). (CVE-2018-2678).
