Vulnerability Details
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 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-2019-2426
DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java
SE Networking component could allow an unauthenticated attacker to obtain
sensitive information resulting in a low confidentiality impact using unknown
attack vectors.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
