According to the versions of the python-pyasn1 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a     Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply     nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE`     (`0x30`) or `SET` (`0x31`) tags with 'Indefinite Length' (`0x80`) markers. This forces the decoder to     recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all     available memory (OOM), crashing the host application. This is a distinct vulnerability from     CVE-2026-23490 (which addressed integer overflows in OID decoding). The fix for CVE-2026-23490     (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this     specific issue.(CVE-2026-30922)

    pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.2, a Denial-of-Service issue has been found     that leads to memory exhaustion from malformed RELATIVE-OID with excessive continuation octets. This     vulnerability is fixed in 0.6.2.(CVE-2026-23490)

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:13512 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.
