Security Bulletin: OpenSSL vulnerabilities affect IBM Unified Extensible Firmware Interface (UEFI)

Summary

IBM System x, Flex and BladeCenter systems have addressed the following OpenSSL vulnerabilities in Unified Extensible Firmware Interface (UEFI).

Vulnerability Details

CVEID: CVE-2017-3738 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. An attacker could exploit this vulnerability to obtain information about the private key. Note: In order to exploit this vulnerability, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136078&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2017-3737 DESCRIPTION: An unspecified vulnerability in multiple Oracle products could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and high availability impact.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136077&gt; for the current score
