CVE-2018-11761 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tika package and not the tika package as distributed by Ubuntu.
In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.
