Debian Bug     : 1007109

Several flaws were discovered in jackson-databind, a fast and powerful JSON
library for Java.

CVE-2020-36518

    Java StackOverflow exception and denial of service via a large depth of
    nested objects.

CVE-2022-42003

    In FasterXML jackson-databind resource exhaustion can occur because of a
    lack of a check in primitive value deserializers to avoid deep wrapper
    array nesting, when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled.

CVE-2022-42004

    In FasterXML jackson-databind resource exhaustion can occur because of a
    lack of a check in BeanDeserializerBase.deserializeFromArray to prevent use
    of deeply nested arrays. An application is vulnerable only with certain
    customized choices for deserialization.

For Debian 10 buster, these problems have been fixed in version
2.9.8-3+deb10u4.

We recommend that you upgrade your jackson-databind packages.

For the detailed security status of jackson-databind please refer to
