"An out-of-bounds write flaw was found in the JPEG image format decoder
in the AWT component in OpenJDK. A specially crafted JPEG image could
cause a Java application to crash or, possibly execute arbitrary code.
An untrusted Java application or applet could use this flaw to bypass
Java sandbox restrictions. (CVE-2016-0483)

An integer signedness issue was found in the font parsing code in the
2D component in OpenJDK. A specially crafted font file could possibly
cause the Java Virtual Machine to execute arbitrary code, allowing an
untrusted Java application or applet to bypass Java sandbox
restrictions. (CVE-2016-0494)

It was discovered that the JAXP component in OpenJDK did not properly
enforce the totalEntitySizeLimit limit. An attacker able to make a
Java application process a specially crafted XML file could use this
flaw to make the application consume an excessive amount of memory.
(CVE-2016-0466)

A flaw was found in the way TLS 1.2 could use the MD5 hash function
for signing ServerKeyExchange and Client Authentication packets during
a TLS handshake. A man-in-the-middle attacker able to force a TLS
connection to use the MD5 hash function could use this flaw to conduct
collision attacks to impersonate a TLS server or an authenticated TLS
client. (CVE-2015-7575)

Multiple flaws were discovered in the Libraries, Networking, and JMX
components in OpenJDK. An untrusted Java application or applet could
use these flaws to bypass certain Java sandbox restrictions.
(CVE-2015-4871 , CVE-2016-0402 , CVE-2016-0448)

Note: This update also disallows the use of the MD5 hash algorithm in
the certification path processing. The use of MD5 can be re-enabled by
removing MD5 from the jdk.certpath.disabledAlgorithms security
property defined in the java.security file."
