SCA: security update for oj (GHSA-35w3-pjm6-wj95)

low Tenable Cloud Security Plugin ID 443713

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, when in object mode, Oj.dump is vulnerable to a heap buffer overflow when serializing Exception
 objects with a large :indent value. The serializer allocates a buffer sized for the object's attributes
 but does not account for the indent bytes added on each write. With indent: 5000, the accumulation of
 5,000-byte indent strings overflows the 13,150-byte heap allocation, corrupting adjacent heap memory. This
 issue has been fixed in version 3.17.2. (CVE-2026-54896)

Solution

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