Security Bulletin: IBM Cloud Manager is affected by the vulnerabilities known as Spectre and Meltdown

Security Bulletin


Summary

IBM Cloud Manager is affected by security vulnerabilities known as Spectre and Meltdown, which can enable CPU data cache timing to be abused to bypass conventional memory security restrictions to gain access to privileged memory that should be inaccessible.

Vulnerability Details

CVEID: CVE-2017-5753
DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow a local authenticated attacker to obtain sensitive information, caused by a bounds check bypass in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to cross the syscall boundary and read data from the CPU virtual memory.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/137052 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N)

CVEID: CVE-2017-5715
DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow a local authenticated attacker to obtain sensitive information, caused by a branch target injection in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to leak memory contents into a CPU cache and read host kernel memory.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/137054 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N)

CVEID: CVE-2017-5754
DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow a local authenticated attacker to obtain sensitive information, caused by a rogue data cache load in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to cause the CPU to read kernel memory from userspace before the permission check for accessing an address is performed.
CVSS Base Score: 5.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/137053 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N)
