SCA: security update for oj (GHSA-475m-ph3x-64gp)

medium Tenable Cloud Security Plugin ID 443622

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. In versions prior to
 3.17.2, Oj.load is vulnerable to heap corruption when parsing a JSON string longer than 2 GB. An integer
 overflow in buf_append_string (buf.h:61) converts the string length to a large negative size_t, causing
 memcpy to copy an astronomically large amount of data out of bounds. This crashes the process and can
 corrupt adjacent heap memory. The issue has been fixed in version 3.17.2. (CVE-2026-54903)

Solution

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