Security Bulletin


Summary

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

Vulnerability Details

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 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-2018-0737
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a cache-timing side channel attack in the RSA Key generation algorithm. An attacker with access to mount cache timing attacks during the RSA key generation process could exploit this vulnerability to recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/141679 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2018-0739
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending specially crafted ASN.1 data with a recursive definition, a remote attacker could exploit this vulnerability to consume excessive stack memory.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/140847 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
