Title:       EGI SVG Advisory - Various Java CVE's with max CVSS score.  

Date:        2015-10-29  



Various vulnerabilities have been publicly announced concerning Java, some of which 
have the maximum CVSS (Common Vulnerability Scoring System) score of 10, but details 
including the attack vectors are not specified. 

We cannot determine the exact effect these vulnerabilities may have in EGI from the 
information currently available. 

Since they have high CVSS scores if and when information becomes available publicly 
there is a fair chance that updating will become urgent, so we are recommending that 
sites update in the coming days. 


Scientific Linux announced 'critical' updates concerning openjdk listing 17 CVE's [R 1]

1 example of a CVE with CVSS score of 10 [R 2]

It would appear that all sources of java (from Oracle and OpenJDK) were vulnerable, 
but fixes are available for most Operating systems. 

Risk category

It is not possible to establish the risk category for EGI as insufficient details o
f the vulnerabilities have been released.  However, since the CVSS score is the maximum 
of 10 for some of them, there is a fair chance that some may be considered at least 'high risk' 
in the EGI environment if and when public information and public exploits become available. 

Affected software

It would appear that this issue affects multiple versions of Java 6, Java 7 and Java 8. 

Versions of Java provided with Scientific Linux, Debian and Ubuntu are stated as being affected. 

See OS provider for more details. 

Component installation information

See appropriate OS provider sites.


Sites are recommended to update to a non-vulnerable version of OpenJDK in the coming days. 


SVG was alerted to this by Ian Neilson
