Package        : jackson-databind
Version        : 2.8.6-1+deb9u10
CVE ID         : CVE-2020-36518
Debian Bug     : 1007109

It was discovered that the implementation of UntypedObjectDeserializer in
jackson-databind, a fast and powerful JSON library for Java, was prone to a
denial of service attack when deeply nested object and array values were
processed. 

For Debian 9 stretch, this problem has been fixed in version
2.8.6-1+deb9u10.

We recommend that you upgrade your jackson-databind packages.
