CVEID:CVE-2016-0494**
DESCRIPTION: *An unspecified vulnerability related to the 2D component has complete confidentiality impact, complete integrity impact, and complete availability impact.
CVSS Base Score: 10
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109944for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVEID:CVE-2016-0483**
DESCRIPTION: *An unspecified vulnerability related to the AWT component has complete confidentiality impact, complete integrity impact, and complete availability impact.
CVSS Base Score: 10
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109945for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVEID:CVE-2015-8472**
DESCRIPTION: *libpng is vulnerable to a buffer overflow, caused by improper bounds checking by the png_get_PLTE() and png_set_PLTE() functions. By persuading a victim to open a specially crafted PNG image, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 6.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109392for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/UI:U/C:L/I:L/A:L)

CVEID:CVE-2016-0466**
DESCRIPTION: *An unspecified vulnerability related to the JAXP component could allow a remote attacker to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109948for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID:CVE-2016-0402**
DESCRIPTION: *An unspecified vulnerability related to the Networking component has no confidentiality impact, partial integrity impact, and no availability impact.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109947for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID:CVE-2015-7575**
DESCRIPTION: *The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials. This vulnerability is commonly referred to as “SLOTH”.
CVSS Base Score: 7.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109415for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/UI:U/C:H/I:L/A:N)

CVEID:CVE-2016-0448**
DESCRIPTION: *An unspecified vulnerability related to the JMX component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N)

CVEID:CVE-2015-8540**
DESCRIPTION: *libpng is vulnerable to a buffer overflow, caused by a read underflow in png_check_keyword in pngwutil.c. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109219for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2015-7981**
DESCRIPTION: *libpng could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read in the png_convert_to_rfc1123 function. An attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/107740for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2015-5041**
DESCRIPTION: *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.
CVSS Base Score: 4.8
