Vulnerability Details
CVEID: CVE-2016-0702
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a side-channel attack against a system based on the
Intel Sandy-Bridge microarchitecture. An attacker could exploit this
vulnerability to recover RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
111144 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
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/

CVEID: CVE-2018-1426
DESCRIPTION: IBM GSKit duplicates the PRNG state across fork() system calls
when multiple ICC instances are loaded which could result in duplicate Session
IDs and a risk of duplicate key material.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
139071 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:H/A:N)
CVEID: CVE-2018-1427
DESCRIPTION: IBM GSKit contains several enviornment variables that a local
attacker could overflow and cause a denial of service.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
139072 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2018-1428
DESCRIPTION: IBM GSKit uses weaker than expected cryptographic algorithms
that could allow an attacker to decrypt highly sensitive information.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
139073 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2018-1447
DESCRIPTION: The GSKit CMS KDB logic fails to salt the hash function
resulting in weaker than expected protection of passwords. A weak password may
be recovered. Note: After update the customer should change password to ensure
the new password is stored more securely. Products should encourage customers
to take this step as a high priority action.
CVSS Base Score: 5.1
