CVE-2018-11796 (opens in a new tab)How to fix?
There is no fixed version for Ubuntu:20.04 tika.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tika package and not the tika package as distributed by Ubuntu.
See How to fix? for Ubuntu:20.04 relevant fixed versions and status.
In Apache Tika 1.19 (CVE-2018-11761), we added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.
