Security Bulletin: IBM Cloud Manager with OpenStack is affected by a OpenSSL vulnerabilities (CVE-2019-1559, CVE-2019-1563, CVE-2019-1547)

Summary

A security vulnerability has been identified in OpenSSL that is used by IBM Cloud Manager with OpenStack. IBM Cloud Manager with OpenStack has addressed this vulnerability.

Vulnerability Details

CVEID: 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: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/157514&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N)

CVEID: CVE-2019-1563 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a padding oracle attack in PKCS7_dataDecode and CMS_decrypt_set1_pkey. By sending an overly large number of messages to be decrypted, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base Score: 3.7
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/167022&gt; for the current score
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)

CVEID: CVE-2019-1547 DESCRIPTION: OpenSSL could allow a local authenticated attacker to obtain sensitive information, caused by the ability to construct an EC group missing the cofactor using explicit parameters instead of using a named curve. An attacker could exploit this vulnerability to obtain full key recovery during an ECDSA signature operation.
CVSS Base Score: 5.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/167020&gt; for the current score
CVSS Environmental Score*: Undefined
