Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on 30 October 2018 and later by the
OpenSSL Project. OpenSSL is used by IBM Worklight and IBM MobileFirst Platform
Foundation. IBM Worklight and IBM MobileFirst Platform Foundation have
addressed the applicable CVEs.
Vulnerability Details
CVE-ID: CVE-2018-0734
Description: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a timing side channel attack in the DSA signature
algorithm. An attacker could exploit this vulnerability using variations in the
signing algorithm to recover the private key.
CVSS Base Score: 3.7
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
152085 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVE-ID: CVE-2019-1559
Description: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by the failure to immediately close the TCP connection
after the hosts encounter a zero-length record with valid padding. An attacker
could exploit this vulnerability using a 0-byte record padding-oracle attack to
decrypt traffic.
CVSS Base Score: 5.8
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
