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 its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
