"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)

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)

Integer signedness issues were discovered in
IndicRearrangementProcessor and IndicRearrangementProcessor2 in the
ICU Layout Engine. A specially crafted font file could cause an
application using ICU to parse untrusted fonts to crash and, possibly,
execute arbitrary code. (CVE-2016-0494)

It was discovered that the password-based encryption (PBE)
implementation in the Libraries component in OpenJDK used an incorrect
key length. This could, in certain cases, lead to generation of keys
that were weaker than expected. (CVE-2016-0475)

A flaw was found in the deserialization of the URL class in the
Networking component of OpenJDK. Deserialization of the specially
crafted data could result in creation of the URL object with an
inconsistent state. An untrusted Java application or applet could use
this flaw to bypass certain Java sandbox restrictions. (CVE-2016-0402)

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)

It was discovered that the RMIConnector and RMIConnectionImpl classes
in the JMX component of OpenJDK could log sensitive information such
as user passwords in its debug log, possibly leading the exposure of
the information. (CVE-2016-0448)"
