tika vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Apache Tika could be made to expose sensitive information over the
network.

Software Description:
- tika: A content analysis toolkit

Details:

It was discovered that Apache Tika's ISA-Tab parser incorrectly handled
file path resolution. An attacker who could place files in a directory that
Tika subsequently parses could use this issue to read arbitrary files
accessible to the Tika process and have their contents emitted into the
extracted text output.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
libtika-java 1.22-2+deb11u1ubuntu0.1~esm2
Available with Ubuntu Pro

Ubuntu 20.04 LTS
libtika-java 1.22-1ubuntu0.1~esm3
Available with Ubuntu Pro

In general, a standard system update will make all the necessary changes.
