An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

  - python: XML External Entity in XML processing plistlib module (CVE-2022-48565)

  - CPython (aka Python) up to 2.7.13 is vulnerable to an integer overflow in the PyString_DecodeEscape     function in stringobject.c, resulting in heap-based buffer overflow (and possible arbitrary code     execution) (CVE-2017-1000158)

  - Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions     prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable     however this has not been confirmed. The vulnerability lies when multiply threads are handling large     amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-     Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without     knowing how much to write. So when a large amount of data is being processed, it is very easy to cause     memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free,     Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a     security vulnerability due to the fact that the attacker must be able to run code, however in some     situations, such as function as a service, this vulnerability can potentially be used by an attacker to     violate a trust boundary, as such the DWF feels this issue deserves a CVE. (CVE-2018-1000030)

  - Lib/zipfile.py in Python through 3.7.2 allows remote attackers to cause a denial of service (resource     consumption) via a ZIP bomb. (CVE-2019-9674)

  - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when     using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for     1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not     affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

  - In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content     retrieved via HTTP. (CVE-2020-27619)

  - The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before     3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and     urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query     parameters using a semicolon (;), they can cause a difference in the interpretation of the request between     the proxy (running with default configuration) and the server. This can result in malicious requests being     cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and     therefore would not include it in a cache key of an unkeyed parameter. (CVE-2021-23336)

  - Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection     against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is     disputed by a third party because the http.server.html documentation page states Warning: http.server is     not recommended for production. It only implements basic security checks. (CVE-2021-28861)

  - There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince     another local or adjacent user to start a pydoc server could access the server and use it to disclose     sensitive information belonging to the other user that they would not normally be able to access. The     highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9,     Python versions before 3.9.3 and Python versions before 3.10.0a7. (CVE-2021-3426)

  - There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP     server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of     Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the     server to the client. The greatest threat that this flaw poses is to application availability.
    (CVE-2021-3733)

  - A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may     allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop,     consuming CPU time. The highest threat from this vulnerability is to system availability. (CVE-2021-3737)

  - A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV     (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This     flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back     to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which     otherwise would not have been possible. (CVE-2021-4189)

  - A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform     Resource Locator (URL) strings into components. The issue involves how the urlparse method does not     sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to     input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1,     3.9.5, 3.8.11, 3.7.11 and 3.6.14. (CVE-2022-0391)

  - An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name     being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by     remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)

  - A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  - read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM     exhaustion when processing malformed Apple Property List files in binary format. (CVE-2022-48564)

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

  - 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 legacy email.utils.parseaddr function in Python through 3.11.4 allows attackers to trigger     RecursionError: maximum recursion depth exceeded while calling a Python object via a crafted argument.
    This argument is plausibly an untrusted value from an application's input data that was supposed to     contain a name and an e-mail address. NOTE: email.utils.parseaddr is categorized as a Legacy API in the     documentation of the Python email package. Applications should instead use the email.parser.BytesParser or     email.parser.Parser class. NOTE: the vendor's perspective is that this is neither a vulnerability nor a     bug. The email package is intended to have size limits and to throw an exception when limits are exceeded;
    they were exceeded by the example demonstration code. (CVE-2023-36632)

  - An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and     3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip     format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile     module reject zip archives which overlap entries in the archive. (CVE-2024-0450)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1556-1 advisory.

  - libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are     required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)

  - An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7,     3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks     during cleanup of permissions-related errors. This means users which can run privileged programs are     potentially able to modify permissions of files referenced by symlinks in some circumstances.
    (CVE-2023-6597)

  - An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and     3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip     format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile     module reject zip archives which overlap entries in the archive. (CVE-2024-0450)

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

The remote host is affected by the vulnerability described in GLSA-202405-01 (Python, PyPy3: Multiple Vulnerabilities)

  - An issue was found in CPython 3.12.0 `subprocess` module on POSIX platforms. The issue was fixed in     CPython 3.12.1 and does not affect other stable releases. When using the `extra_groups=` parameter with an     empty list as a value (ie `extra_groups=[]`) the logic regressed to not call `setgroups(0, NULL)` before     calling `exec()`, thus not dropping the original processes' groups before starting the new process. There     is no issue when the parameter isn't used or when any value is used besides an empty list. This issue only     impacts CPython processes run with sufficient privilege to make the `setgroups` system call (typically     `root`). (CVE-2023-6507)

  - An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7,     3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks     during cleanup of permissions-related errors. This means users which can run privileged programs are     potentially able to modify permissions of files referenced by symlinks in some circumstances.
    (CVE-2023-6597)

  - An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

  - An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x     before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If     a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly,     there is a brief window where the SSLSocket instance will detect the socket as not connected and won't     initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not     be authenticated if the server-side TLS peer is expecting client certificate authentication, and is     indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the     buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path     requires that the connection be closed on initialization of the SSLSocket.) (CVE-2023-40217)

  - An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to     os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible     cases in which an application would have rejected a filename for security reasons in Python 3.10.x or     earlier, but that filename is no longer rejected in Python 3.11.x. (CVE-2023-41105)

  - An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and     3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip     format to create a zip-bomb with a high compression ratio.
