Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect AIX

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

SUMMARY:

There are multiple vulnerabilities in IBM SDK Java Technology Edition,
Versions 7, 7.1, 8 that are used by AIX. These issues were disclosed
as part of the IBM Java SDK updates in January 2019.

    https://vulners.com/cve/CVE-2018-1890
DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX 
    platform uses absolute RPATHs which may facilitate code injection and 
    privilege elevation by local users.
CVSS Base Score: 5.6
CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/152081
    for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-12549
    https://vulners.com/cve/CVE-2018-12549
    https://vulners.com/cve/CVE-2018-12549
DESCRIPTION: Eclipse OpenJ9 could allow a remote attacker to execute 
    arbitrary code on the system, caused by the failure to omit a null 
    check on the receiver object of an Unsafe call when accelerating it. 
    An attacker could exploit this vulnerability to execute arbitrary 
    code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/157513
    for the current score

CVEID: CVE-2018-12547
    https://vulners.com/cve/CVE-2018-12547
    https://vulners.com/cve/CVE-2018-12547
DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by 
    improper bounds checking by the jio_snprintf() and jio_vsnprintf() 
    functions. 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

    https://vulners.com/cve/CVE-2018-11212
    https://vulners.com/cve/CVE-2018-11212
DESCRIPTION: libjpeg is vulnerable to a denial of service, caused by 
    divide-by-zero error in the alloc_sarray function in jmemmgr.c. By 
    persuading a victim to open a specially-crafted file, a remote 
    attacker could exploit this vulnerability to cause the application to 
    crash.

AFFECTED PRODUCTS AND VERSIONS:

    AIX 7.1, 7.2
    VIOS 2.2.x

    The following fileset levels (VRMF) are vulnerable, if the
    respective Java version is installed:
    For Java7:    Less than 7.0.0.640
    For Java7.1:  Less than 7.1.0.440
    For Java8:    Less than 8.0.0.530

    Note: To find out whether the affected Java filesets are installed
    on your systems, refer to the lslpp command found in AIX user's guide.

    Example:  lslpp -L | grep -i java

REMEDIATION:

    Note: Recommended remediation is to always install the most recent
    Java package available for the respective Java version.
