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

    `Element.findall()` and fully-consumed `Element.iterfind()` exhibit `O(n^2)` time complexity when using     XPath index predicates (e.g. `[1]`, `[last()]`, `[last()-N]`) on XML documents with many same-tag     siblings. `Element.find()` is only affected when the first match is near the end of the sibling list, such     as with `[last()]` or `[last()-N]`; `.//item[1]` short-circuits after the first match.(CVE-2026-6879)

    In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks.
    An affected system that extracts content from untrusted tar files could end up writing files with an     unexpected uid/gid despite the user passing filter='data' to the extract() function.(CVE-2026-4360)

    `xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding     protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this     vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.(CVE-2026-7210)

    The ftpcp() function in Lib/ftplib.py was not updated when     CVE-2021-4189 was fixed. While makepasv() was patched to replace     server-supplied PASV host addresses with the actual peer address     (getpeername()[0]), ftpcp() still calls parse227() directly and passes     the raw attacker-controllable IP address and port to target.sendport(). This patch is related to     CVE-2021-4189.(CVE-2026-8328)

    unicodedata.normalize() can take excessive CPU time when processing     specially crafted Unicode input containing long runs of combining characters     with alternating Canonical Combining Class values.
    This affects all normalization forms.(CVE-2026-3276)

    When using the 'configparser' module to write configuration files     containing multi-line text values with carriage return characters (\r) the     resulting file could be injected with unexpected keys and values if the     attacker controls the written value.(CVE-2026-0864)

    When using the 'tarfile' module with a file opened in 'streaming mode' (mode='r|') the tarfile module did     not properly handle EOF, making archive parsing take exponentially longer.(CVE-2026-11972)

    tarfile.extractall() with the 'data' or 'tar'      filter could be bypassed by a crafted archive where a hardlink     references a symlink stored at a deeper name than the hardlink itself.
    The extraction fallback validated the symlink at it's archived location     but recreated it at the hardlink's shallower     path, letting a relative      target the filter judged contained escape the destination directory.
    This allowed a malicious tar archive to create a symlink pointing     outside the destination, enabling out-of-destination file reads or     writes. This was an incomplete fix of CVE-2025-4330.(CVE-2026-11940)

    http.cookies.Morsel.js_output() returns an inline script snippet and only escapes ' for JavaScript     string context. It does not neutralize the HTML parser-sensitive sequence /script inside the     generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie     value.(CVE-2026-6019)

    Use-after-free (UAF) was possible in the `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and     `gzip.GzipFile` when a memory allocation fails with a `MemoryError` and the decompression instance is re-     used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the     dangling pointer in this specific error condition.

    The vulnerability is only present if the program re-uses decompressor instances across multiple     decompression calls even after a `MemoryError` is raised during decompression. Using the helper functions     to one-shot decompress data such as `lzma.decompress()`, `bz2.decompress()`, `gzip.decompress()`, and     `zlib.decompress()` are not affected as a new decompressor instance is used per call. If the decompressor     instance is not re-used after an error condition, this usage is similarly not vulnerable.(CVE-2026-6100)

    bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the     resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to     resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash     the process when processing untrusted data.(CVE-2026-9669)

    tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or     directory-like names, to redirect later archive members outside the intended extraction directory. This     allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination     directory, subject to the permissions of the extracting process.(CVE-2026-7774)

    The webbrowser.open() API would accept leading dashes in the URL which     could be handled as command line options for certain web browsers. New     behavior rejects leading dashes. Users are recommended to sanitize URLs     prior to passing to webbrowser.open().(CVE-2026-4519)

    The import hook in CPython that handles legacy *.pyc files (SourcelessFileLoader) is incorrectly handled     in FileLoader (a base class) and so does not use io.open_code() to read the .pyc files. sys.audit handlers     for this audit event therefore do not fire.(CVE-2026-2297)

    The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The     Morsel.update(), |= operator, and unpickling paths were not patched, allowing control characters to bypass     input validation. Additionally, BaseCookie.js_output() lacked the output validation applied to     BaseCookie.output().(CVE-2026-3644)

    When an Expat parser with a registered ElementDeclHandler parses an inline     document type definition containing a deeply nested content model a C stack     overflow occurs.(CVE-2026-4224)

Tenable has extracted the preceding description block directly from the EulerOS python3 security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1774 advisory.

    The tarfile module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while     processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a     crafted tar archive being misinterpreted by the tarfile module compared to other implementations.
    (CVE-2025-13462)

    CR/LF bytes were not rejected by HTTP client proxy tunnel headers or host. (CVE-2026-1502)

    The profiling.sampling module (Python 3.15+) and asyncio introspection capabilities (3.14+, python -m     asyncio ps and python -m asyncio pstree) features could be used to read and write addresses in a     privileged process if that process connected to a malicious or infected Python process via the remote     debugging feature. This vulnerability requires persistently and repeatedly connecting to the process to be     exploited, even after the connecting process crashes with high likelihood due to ASLR. (CVE-2026-5713)

    http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes  for JavaScript     string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated     script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.
    (CVE-2026-6019)

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:1818-1 advisory.

    Security issues fixed:

    - CVE-2026-1502: HTTP client proxy tunnel headers not validated for CR/LF (bsc#1261969).
    - CVE-2026-3446: base64 decoding stops at first padded quad by default and ignores other information that     could be       processed (bsc#1261970).
    - CVE-2026-3479: improper resource argument validation in `pkgutil.get_data()` can lead to path traversal     (bsc#1259989).
    - CVE-2026-4786: URLs prefixed with `%action` can pass the dash-prefix safety check and allow for command     injection       (bsc#1262319).
    - CVE-2026-6019: `BaseCookie.js_output()` does not neutralize characters in cookie values embedded in JS     (bsc#1262654).
    - CVE-2026-6100: use-after-free in `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile`     when process is       under memory pressure(bsc#1262098).

    Other updates and bugfixes:

    - Rewrite structure of Python interpreter packages. `python3*` symbols should be now provided by real     python3 packages       and its subpackages instead of the virtual provides (bsc#1258364).

    Mitgation of CVE-2026-4519 was incomplete. If the URL contained '%action' the mitigation could be bypassed     for certain browser types the 'webbrowser.open()' API could have commands injected into the underlying     shell. See CVE-2026-4519 for details.(CVE-2026-4786)

    When folding a long comment in an email header containing exclusively unfoldable characters, the     parenthesis would not be preserved. This could be used for injecting headers into email messages where     addresses are user-controlled and not sanitized.(CVE-2025-11468)

    DISPUTED: The project has clarified that the documentation was incorrect, and that pkgutil.get_data() has     the same security model as open(). The documentation has been updated to clarify this point. There is no     vulnerability in the function if following the intended security model.

    pkgutil.get_data() did not validate the resource argument as documented, allowing path     traversals.(CVE-2026-3479)

    When an Expat parser with a registered ElementDeclHandler parses an inline     document type definition containing a deeply nested content model a C stack     overflow occurs.(CVE-2026-4224)

    User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in     the data URL mediatype.(CVE-2025-15282)
