Security Bulletin
Summary
There is a security advisory for openSSL_1.0.2p which is used by IBM Tivoli Netcool System Service Monitors/Application Service Monitors 4.0.1
Vulnerability Details
CVEID: CVE-2018-5407
DESCRIPTION: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by executing engine sharing on Simultaneous Multithreading (SMT) architecture. By using the PortSmash new side-channel attack, an attacker could run a malicious process next to legitimate processes using the architecture’s parallel thread running capabilities to leak encrypted data from the CPU's internal processes.
Note: This vulnerability is known as PortSmash.
CVSS Base score: 5.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/152484 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2020-1967
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. By passing specially crafted data to the SSL_check_chain() function during or after a TLS 1.3 handshake, a remote attacker could exploit this vulnerability to cause server or client applications to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/180181 for the current score.

CVEID: 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: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/152085 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/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 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/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 for the current score.
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 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
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 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N)
CVEID: CVE-2018-0735
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the ECDSA 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: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/152086 for the current score.
