Multiple security issues were found in jackson-databind, a Java library to parse JSON and other data formats which could result in information disclosure or the execution of arbitrary code.
For the stable distribution (stretch), these problems have been fixed in version 2.8.6-1+deb9u5.
We recommend that you upgrade your jackson-databind packages.
