Debian LTS Advisory DLA-3207-1 [email protected]

Package : jackson-databind
Version : 2.9.8-3+deb10u4
CVE ID : CVE-2020-36518 CVE-2022-42003 CVE-2022-42004
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
its security tracker page at:
