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

IV72872 (CVE-2015-5041)
Workarounds and Mitigations
For CVE-2015-7575, users of Java 7 and later can address the issue by updating
the /jre/lib/security/java.security file as follows (both steps are required):
Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g.
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5
Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
Java 6 requires code changes in the JSSE component in addition to the
java.security file modifications, so upgrading the JDK is the only solution.
