and 8 that are used by Rational Publishing Engine.
Vulnerability Details
CVEID: CVE-2016-0705
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a
double-free error when parsing DSA private keys. An attacker could exploit this
vulnerability to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
111140 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2017-3732
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a carry propagating bug in the x86_64 Montgomery
squaring procedure. An attacker could exploit this vulnerability to obtain
information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
121313 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2017-3736
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a carry propagation flaw in the x86_64 Montgomery
squaring function bn_sqrx8x_internal(). An attacker with online access to an
unpatched system could exploit this vulnerability to obtain information about
the private key.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
134397 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2018-1656
DESCRIPTION: The IBM Java Runtime Environment's Diagnostic Tooling Framework
for Java (DTFJ) does not protect against path traversal attacks when extracting
compressed dump files.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144882 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N)
CVEID: CVE-2018-12539
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.
CVSS Base Score: 8.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
148389 for the current score
CVSS Environmental Score*: Undefined
