Title:       EGI SVG 'ALERT' [TLP:WHITE] Various Intel Vulnerabilities CVE-2017-5712 and others [EGI-SVG-CVE-2017-5712] 

Date:        2017-12-06 
Updated:     


Affected software and risk
==========================

Various intel vulnerabilities.

Package :  Intel firmware
CVE ID  :  CVE-2017-5705, CVE-2017-5708, CVE-2017-5711, CVE-2017-5712

Various intel vulnerabilities have been identified by Intel, which allow privilege escalation. [R 1]   
At least one site has been identified which has the vulnerable CPU type in the cluster. 
 

Actions required/recommended
============================

Sites should take a look at [R 1] and consider whether any actions are necessary on their particular site.  

Affected software details
=========================

See [R 1]

For a list of vulnerable CPUs see [R 2] 

More information
================

One (CVE-2017-5712) is in certain circumstances possibly remotely exploitable. 
The others require physical access to the appropriate machine.  
In addition, CVE-2017-5689 (INTEL-SA-00075) about which SVG issued an advisory [R 4] 
may make CVE-2017-5712 more likely to be remotely exploitable.  


Sites should see [R 1].

For a list of vulnerable CPUs see [R 2] 

An intel detection tool can be used to check if firmware is vulnerable, which can be downloaded from [R 3].  
This tool is available for multiple platforms including linux.



Mitigation
==========

It is thought that the ability to exploit these vulnerabilities in the EGI infrastructure is limited. 

If any site finds that these are easily exploitable in their site configuration, particularly if this 
is likely to be the case at other sites, please let us (SVG) know. 

TLP and URL
===========
