high Nessus Plugin ID 328359

Synopsis

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

Description

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42079 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.

Security Fix(es):

* ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution (CVE-2026-11332)
* automation-controller: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite (CVE-2026-8643)
* automation-controller: urllib3: Denial of Service due to excessive HTTP response decompression (CVE-2026-44432)
* automation-platform-ui: fast-uri: Path traversal vulnerability allows bypass of security policies (CVE-2026-6321)
* python3.12-pulpcore: relative_path_validator bypass via directory traversal in FilesystemExport (CVE-2026-12701)
* receptor: golang.org/x/net/html: Cross-Site Scripting via HTML parsing bypass (CVE-2026-27136)
* receptor: golang.org/x/net/html: Arbitrary code execution via Cross-Site Scripting (CVE-2026-25681)
* receptor: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145)
* receptor: Go net package: Denial of Service via long CNAME response in LookupCNAME (CVE-2026-33811)
* receptor: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing (CVE-2026-39821)
* receptor: Go crypto/x509: Denial of Service via inefficient certificate chain validation (CVE-2026-32281)
