critical Nessus Plugin ID 379080

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2026:99008 advisory.

Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language.

* automation-controller: GitPython 3.1.30 before 3.2.0 Command Injection via Remote.pull() Refspec (CVE-2026-110858)
* automation-controller: GitPython: Denial of Service via regular expression backtracking in date parsing (CVE-2026-110856)
