Security Bulletin: IBM Event Streams is affected by OpenSSL vulnerabilities

Summary

IBM Event Streams has addressed the following vulnerabilities in the OpenSSL versions shipped.

Vulnerability Details

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
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2019-1549 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by the failure to include protection in the event of a fork() system call to ensure that the parent and child processes do not share the same RNG state. 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/167021&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-2019-1552 DESCRIPTION: OpenSSL could allow a local attacker to bypass security restrictions, caused by the building of . mingw programs or Windows programs with world writable path defaults. An attacker could exploit this vulnerability to modify default configuration, insert CA certificates, modify (or even replace) existing engine modules.
CVSS Base Score: 2.9
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/164498&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/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)
