K000135852 : FasterXML jackson-databind vulnerability CVE-2022-42003

Security Advisory Description

In FasterXML jackson-databind before 2.14.0-rc1, 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. Additional fix version in 2.13.4.1 and 2.12.17.1 (CVE-2022-42003)

Impact

This issue could allow an attacker to benefit from resource exhaustion when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled due to unchecked primitive value deserializers to avoid deep wrapper array nesting.
