SUMMARY:

    There are multiple vulnerabilities in IBM SDK Java Technology Edition,
    Versions 6, 7, 7.1, 8 that are used by AIX. These issues were disclosed
    as part of the IBM Java SDK updates in January 2016 and includes the
    vulnerability commonly referred to as "SLOTH".


===============================================================================

VULNERABILITY DETAILS:

    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.

    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.
