IBM SDK, Java Technology Edition 7.1.5.18 and 8.0.8.0 could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization flaw. By sending specially-crafted data, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 236069.
The following flaw was reported for IBM JDK:
A flaw in the IBM J9 JVM allows code to invoke non-public interface methods under certain circumstances. Untrusted code could potentially exploit this. This could lead to sensitive data being exposed to an attacker, or the attacker being able to inject bad data.
http://www-01.ibm.com/support/docview.wss?uid=swg21974193 http://www.ibm.com/developerworks/java/jdk/alerts/#IBMSecurityUpdateJanuary2016
This flaw could allow an untrusted Java application or applet to bypass certain Java sandbox restrictions.
Issue was fixed in IBM JDK 6 SR16-FP20, 7 SR9-FP30, 7R1 SR3-FP30, and 8 SR2-FP10.
Adam Gowdiak (Security Explorations) reported that the fix for IBM JDK issue CVE-2013-5456 (bug 1027748), also known as "Issue 70", did not correctly address the problem. Applied fix only restricted access to the vulnerable package, rather then addressing the underlying problem of running untrusted code inside doPrivileged block.

IBM SDK, Java Technology Edition Version 7.0.0.0 through 7.0.10.55, 7.1.0.0 through 7.1.4.55, and 8.0.0.0 through 8.0.6.0 could allow a local authenticated attacker to execute arbitrary code on the system, caused by DLL search order hijacking vulnerability in Microsoft Windows client. By placing a specially-crafted file in a compromised folder, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 172618.
A buffer overflow flaw was fixed in IBM JDK 6 SR16-FP25, 7 SR9-FP40, 7R1 SR3-FP40, and 8 SR3:
CVEID: CVE-2016-0264 DESCRIPTION: A buffer overflow vulnerability in the IBM JVM facilitates arbitrary code execution under certain limited circumstances. CVSS Base Score: 5.6 CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

IBM Java Security Components in IBM SDK, Java Technology Edition 8 before SR1 FP10, 7 R1 before SR3 FP10, 7 before SR9 FP10, 6 R1 before SR8 FP7, 6 before SR16 FP7, and 5.0 before SR16 FP13 stores plaintext information in memory dumps, which allows local users to obtain sensitive information by reading a file.
An information leak flaw was found in the IBM JDK Java Security Components. Upstream security bulletin describes the issue as:
IBM Java Security Components could allow an attacker with physical access to the system to obtain sensitive information from the Kerberos Credential Cache.
