Security Bulletin: Vulnerabilities in OpenSSL affect GCM16 & GCM32 KVM Switch Firmware

Security Bulletin


Summary

IBM GCM16 & GCM32 KVM Switch Firmware have addressed the following vulnerabilities in OpenSSL.

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 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/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)
