"The version of AOS installed on the remote host is prior to 7.0.1.15. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-7.0.1.15 advisory.

  - urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient
    handling of large HTTP responses by reading the content in chunks, rather than loading the entire response
    body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-
    Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library
    decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and
    prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to
    drain the connection and decompress the content unnecessarily. This decompression occurred even before any
    read methods were called, and configured read limits did not restrict the amount of decompressed data. As
    a result, there was no safeguard against decompression bombs. A malicious server could exploit this to
    trigger excessive resource consumption on the client. Applications and libraries are affected when they
    stream content from untrusted sources by setting `preload_content=False` when they do not disable
    redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content
    of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable
    redirects by setting `redirect=False` for requests to untrusted source. (CVE-2026-21441)

  - Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in
    Apache Commons FileUpload. This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from
    2.0.0-M1 before 2.0.0-M4. Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the
    issue. (CVE-2025-48976)

  - A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte
    usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils
    utilities writing to the password database. (CVE-2025-14104)

  - urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0,
    the number of links in the decompression chain was unbounded allowing a malicious server to insert a
    virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation
    for the decompressed data. This vulnerability is fixed in 2.6.0. (CVE-2025-66418)

  - urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the
    Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the
    efficient handling of large HTTP responses by reading the content in chunks, rather than loading the
    entire response body into memory at once. When streaming a compressed response, urllib3 can perform
    decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd).
    The library must read compressed data from the network and decompress it until the requested chunk size is
    met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for
    the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of
    highly compressed data in a single operation. This can result in excessive resource consumption (high CPU
    usage and massive memory allocation for the decompressed data. (CVE-2025-66471)
