Summary
There are vulnerabilities in the Open Source OpenSSL that is used by the IBM
PureApplication Systems/Service
Vulnerability Details
CVEID: CVE-2017-3738
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an overflow bug in the AVX2 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. An attacker could
exploit this vulnerability to obtain information about the private key. Note:
In order to exploit this vulnerability, the server would have to share the
DH1024 private key among multiple clients, which is no longer an option since
CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
136078 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/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
