Amazon Linux 2 : runfinch-finch (ALASDOCKER-2026-161)

high Nessus Plugin ID 377962

Synopsis

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

Description

The version of runfinch-finch installed on the remote host is prior to 1.19.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2DOCKER-2026-161 advisory.

 go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests. (CVE-2026-93450)

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 runfinch-finch' or or 'yum update --advisory ALAS2DOCKER-2026-161' to update your system.
