Is Jira 7.x affected by CVE-2016-5582?

Question

Hello,

i noticed this vulnerability warning

It reads

unspecified vulnerability in Oracle Java SE 6u121, 7u111, 8u102; and Java SE Embedded 8u101 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Hotspot, a different vulnerability than CVE-2016-5573.

So "Hotspot" is "the open-source Java VM implementation by Oracle".

Is that the JRE that ships with Jira? Or is this another JRE?

I am uncertain if this means there is an attack vector when running a Jira version that uses this Java version.

By the way: Is there a handy table somewhere on the internet listing which Jira version ships with which version of the JRE?

Thanks in advance

Jens

Hey @Jens Kisters __SeibertSolutions,

The Hotspot version does come bundled with the installer.

Unfortunately we do not maintain a list of which JRE versions were bundled with which version of Jira. There's also the chance that Jira was installed without using the .bin/.exe installers (the .tar.gz does not include a JRE) or that the JAVA_HOME has been modified to use the system Java. Because of that, I wouldn't want to say straightaway "Jira 7.__ is ok" since you won't know for sure that the bundled JRE is in use without looking.

The safest advice is to check the System Info page for each instance you're concerned about and check the Java Version string.

All that being said, I checked these versions manually:

* Jira 7.1.0 bundled with 8u51
* Jira 7.2.0 bundled with 8u102
* Jira 7.3.0 bundled with 8u102
* Jira 7.4.0 bundled with 8u102
* Jira 7.5.0 bundled with 8u102
* Jira 7.6.0 bundled with 8u102 -> 7.6.11 bundled with 8u181
* Jira 7.7.0 bundled with 8u102 -> 7.7.4 bundled with 8u102
* Jira 7.8.0 bundled with 8u102
* Jira 7.9.0 bundled with 8u102
* Jira 7.10.0 bundled with 8u102
* Jira 7.11.0 bundled with 8u102 -> Jira 7.11.2 bundled with 8u102
* Jira 7.12.0 bundled with 8u102 -> 7.12.3 bundled with 8u181
* Jira 7.13.0 bundled with 8u181

So if you're not running 7.6.11, 7.12.3, or 7.13/above, you're likely on u102 (again - check the System Info page to confirm).

I don't know the specifics of how that attack vector might be utilized, but it does sound like this is an ideal time to look at a bugfix or version upgrade for many environments.

Cheers,
Daniel

Hi Gonchik,

my interpretation of your response is:

"just update the JRE, its not a big deal"

Is that correct?

I am currently trying to decide if i have to, because we are talking about a large number of server instances and before managing downtimes with a lot of clients i'd like to know if the vulnerability does affect our jira systems.

Plus i am not sure we are elegible to upgrade without paying oracle for it.

kind regards

Jens

Hi!

Let's check when was delivered the 8u102,

https://www.oracle.com/technetwork/java/javase/8u102-relnotes-3021767.html

update JDK for one system it can be done in 2 min with 2-3 min downtime of this node. Of course, if you are using Jira DC, it is not your issue.
