Date Reported:

03 Oct 2019

Affected Packages:

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 940498, Bug 941530.
In Mitre's CVE dictionary: CVE-2019-14540, CVE-2019-16335, CVE-2019-16942, CVE-2019-16943.

More information:

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.
