Security Bulletin
Summary
There are vulnerabilities in Java to which the IBM FlashSystem™ V840 and FlashSystem V9000 are susceptible (CVE-2018-2783, CVE-2018-1517, CVE-2018-12539, CVE-2018-3180, and CVE-2018-12547). An exploit of CVE-2018-12547 could make the system susceptible to a buffer overflow which could allow a remote attacker to execute arbitrary code on the system or cause an application crash. An exploit of CVE-2018-2783 or CVE-2018-3180 could allow an attacker to impact confidentiality, integrity, and availability. An exploit of CVE-2018-1517 could allow an attacker to inflict a denial-of-service attack. Finally, an exploit of CVE-2018-12539 could allow execute untrusted native code and gain elevated privileges on the system.
Vulnerability Details
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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/157512 for 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)
DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. An attacker could exploit this vulnerability to execute untrusted native code and gain elevated privileges on the system.
