Amazon Linux 2 : jackson (ALAS-2025-2934)

high Nessus Plugin ID 243256

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of jackson installed on the remote host is prior to 1.9.4-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2934 advisory.

 jackson-core contains core low-level incremental (streaming) parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large.
 jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. As a workaround, users should avoid parsing input files from untrusted sources.
 (CVE-2025-52999)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update jackson' to update your system.
