SCA: security update for oj (GHSA-9ppp-w3g4-fh4q)

low Tenable Cloud Security Plugin ID 443712

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to 3.17.2,
 Oj::Doc iterators (each_value, each_child, each_leaf) were vulnerable to a heap use-after-free. When a
 Ruby block yielded during iteration calls doc.close or d.close, the document's heap memory is freed while
 the C iterator is still running. When control returns from the block, the iterator reads from the freed
 region, producing a use-after-free accessible from pure Ruby. This issue has been fixed in version 3.17.2.
 (CVE-2026-54897)

Solution

Update the oj library and its related packages to version 3.17.3 or later.
