"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-790 advisory.

    Directory traversal vulnerability in the (1) extract and (2) extractall functions in the tarfile module in
    Python allows user-assisted remote attackers to overwrite arbitrary files via a .. (dot dot) sequence in
    filenames in a TAR archive, a related issue to CVE-2001-1267. (CVE-2007-4559)

    The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special
    character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some
    applications, an attacker can bypass a protection mechanism in which application access is granted only
    after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be
    used for signup). This occurs in email/_parseaddr.py in recent versions of Python. (CVE-2023-27043)

    The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses were
    designated as globally reachable or private. This affected the is_private and is_global properties of
    the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network
    classes, where values wouldn't be returned in accordance with the latest information from the IANA
    Special-Purpose Address Registries.

    CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended
    behavior. (CVE-2024-4032)

    There is a MEDIUM severity vulnerability affecting CPython.





    Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are
    vulnerable to ReDoS via specifically-crafted tar archives. (CVE-2024-6232)

    There is a MEDIUM severity vulnerability affecting CPython.

    Theemail module didn't properly quote newlines for email headers whenserializing an email message allowing
    for header injection when an emailis serialized. (CVE-2024-6923)

    There is a LOW severity vulnerability affecting CPython, specifically the'http.cookies' standard library
    module.

    When parsing cookies that contained backslashes for quoted characters inthe cookie value, the parser would
    use an algorithm with quadraticcomplexity, resulting in excess CPU resources being used while parsing
    thevalue. (CVE-2024-7592)

    There is a severity vulnerability affecting the CPython zipfilemodule.

    When iterating over names of entries in a zip archive (for example, methodsof zipfile.ZipFile like
    namelist(), iterdir(), extractall(), etc)the process can be put into an infinite loop with a
    maliciously craftedzip archive. This defect applies when reading only metadata or extractingthe contents
    of the zip archive. Programs that are not handlinguser-controlled zip archives are not affected.
    (CVE-2024-8088)
