Akira Ajisaka commented on HADOOP-12705:
----------------------------------------
bq. Can we upgrade to jackson v2.7.6 or v2.8.0 - these versions coming soon,
fix an XML Entity Expansion vulnerability?
Is there any detailed information that there is a vulnerability and it will be
fixed in 2.7.6/2.8.0? I can only found CVE-2016-3720 and it is fixed in 2.7.4.
bq. Would it be possible to remove the dependency on jackson 1.9.13 too
I'm thinking this can be done in a separate jira.
> Upgrade Jackson 2.2.3 to 2.5.3 or later

> There's no rush to do this; this is just the JIRA to track versions. However,
> without the upgrade, things written for Jackson 2.4.4 can break ( SPARK-12807)
> being Jackson, this is a potentially dangerous update.
