"According to the versions of the python3 packages installed, the EulerOS Virtualization installation on the remote host
is affected by the following vulnerabilities :

    There is a defect in the CPython 'tarfile' module affecting the 'TarFile' extraction and entry enumeration
    APIs. The tar implementation would process tar archives with negative offsets without error, resulting in
    an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability
    can be mitigated by including the following patch after importing the 'tarfile' module:
    https://gist.github.com/sethmlarson/1716ac5b82b73dbcbf23ad2eff8b33e1(CVE-2025-8194)

    During an address list folding when a separating comma ends up on a folded line and that line is to be
    unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the
    separating comma remains a plan comma. This can result in the address header being misinterpreted by some
    mail servers.(CVE-2025-1795)

    The html.parser.HTMLParser class had worse-case quadratic complexity when processing certain crafted
    malformed inputs potentially leading to amplified denial-of-service.(CVE-2025-6069)

    There is an issue in CPython when using `bytes.decode('unicode_escape', error='ignore|replace')`. If you
    are not using the 'unicode_escape' encoding or an error handler your usage is not affected. To work-around
    this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except
    catching the DecodeError.(CVE-2025-4516)

    The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing
    hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled
    SSRF if a URL is processed by more than one URL parser.(CVE-2024-11168)
