"More deserialization flaws were discovered in jackson-databind
relating to the classes in com.zaxxer.hikari.HikariConfig,
com.zaxxer.hikari.HikariDataSource, commons-dbcp and
com.p6spy.engine.spy.P6DataSource, which could allow an
unauthenticated user to perform remote code execution. The issue was
resolved by extending the blacklist and blocking more classes from
polymorphic deserialization.

For Debian 8 'Jessie', these problems have been fixed in version
2.4.2-2+deb8u9.

We recommend that you upgrade your jackson-databind packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
