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/109392 for 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/109415 for the current score

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/109219 for the current score
CVSS Environmental Score*: Undefined

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/107740 for 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
