5 security issues in sid high

There are 5 open security issues in sid.

5 important issues:

CVE-2026-7210: `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-2026-8328: 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-2025-12781: When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. This behavior matches what is recommended in earlier base64 RFCs, but newer RFCs now recommend either dropping characters outside the specified base64 alphabet or raising an error. The old behavior has the possibility of causing data integrity issues. This behavior can only be insecure if your application uses an alternate base64 alphabet (without "+/"). If your application does not use the "altchars" parameter or the urlsafe_b64decode() function, then your application does not use an alternative base64 alphabet. The attached patches DOES NOT make the base64-decode behavior raise an error, as this would be a change in behavior and break existing programs. Instead, the patch deprecates the behavior which will be replaced with the newly recommended behavior in a future version of Python. Users are recommended to mitigate by verifying user-controlled inputs match the base64 alphabet they are expecting or verify that their application would not be affected if the b64decode() functions accepted "+" or "/" outside of altchars.
CVE-2025-15366: The imaplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters.
CVE-2025-15367: The poplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters.

version in VCS is newer than in repository, is it time to upload? normal

vcswatch reports that this package seems to have a new changelog entry (version 3.14.5-2, distribution UNRELEASED) and new commits in its VCS. You should consider whether it's time to make an upload.

Here are the relevant commit messages:

commit dbefbfae880b397a985947bfc3fca78ac46acdf0
Merge: 7070f81 cf25fcc
Author: Stefano Rivera <stefanor@debian.org>
Date:   Mon May 11 13:01:22 2026 +0000

    Merge branch 'drop-libnsl-dev-3.14' into 'python3.14'
    
    Drop libnsl-dev build-dependency
    
    See merge request cpython-team/python3!43

commit cf25fcc22aa40387f8170d1de3238a2c8c4ddd63
Author: Colin Watson <cjwatson@debian.org>
Date:   Mon May 11 10:17:08 2026 +0100

    Drop libnsl-dev build-dependency
    
    This was added in Python 3.12 to fix https://bugs.debian.org/1065128.
    However, it's superfluous in Python 3.13 since the nis module was
    dropped as one of the "dead batteries"
    (https://peps.python.org/pep-0594/#nis).
