Vulnerability Details

CVEID: 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&gt; 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)

CVEID: 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
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/157512&gt; for the current score
