The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without     proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks     and race conditions. (CVE-2025-6020)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of AOS installed on the remote host is prior to 7.0.1.8. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.0.1.8 advisory.

  - inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9840)

  - setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python     packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version     78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the     permissions of the process running the Python code, which could escalate to remote code execution     depending on the context. Version 78.1.1 fixes the issue. (CVE-2025-47273)

  - A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under     certain circumstances when the XML schematron has the <sch:name path=.../> schema elements. This flaw     allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the     program's crash using libxml or other possible undefined behaviors. (CVE-2025-49794)

  - A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can     trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that     can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to     sensitive data being corrupted in memory. (CVE-2025-49796)

  - A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations     can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of     service when processing crafted input. (CVE-2025-6021)
