CVE-2023-38898 1 Python 1 Python 2024-05-17 N/A 5.3 MEDIUM
An issue in Python cpython v.3.7 allows an attacker to obtain sensitive information via the _asyncio._swap_current_task component. NOTE: this is disputed by the vendor because (1) neither 3.7 nor any other release is affected (it is a bug in some 3.12 pre-releases); (2) there are no common scenarios in which an adversary can call _asyncio._swap_current_task but does not already have the ability to call arbitrary functions; and (3) there are no common scenarios in which sensitive information, which is not already accessible to an adversary, becomes accessible through this bug.
CVE-2023-36632 1 Python 1 Python 2024-05-17 N/A 7.5 HIGH
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-2021-28861 2 Fedoraproject, Python 2 Fedora, Python 2024-05-17 N/A 7.4 HIGH
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-2019-13404 2 Microsoft, Python 2 Windows, Python 2024-05-17 9.3 HIGH 7.8 HIGH
The MSI installer for Python through 2.7.16 on Windows defaults to the C:\Python27 directory, which makes it easier for local users to deploy Trojan horse code. (This also affects old 3.x releases before 3.5.) NOTE: the vendor's position is that it is the user's responsibility to ensure C:\Python27 access control or choose a different directory, because backwards compatibility requires that C:\Python27 remain the default for 2.7.x
CVE-2017-18207 1 Python 1 Python 2024-05-17 4.3 MEDIUM 6.5 MEDIUM
The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications "need to be prepared to handle a wide variety of exceptions.
CVE-2017-17522 1 Python 1 Python 2024-05-17 6.8 MEDIUM 8.8 HIGH
Lib/webbrowser.py in Python through 3.6.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a software maintainer indicates that exploitation is impossible because the code relies on subprocess.Popen and the default shell=False setting
CVE-2023-6507 1 Python 1 Python 2024-05-07 N/A 4.9 MEDIUM
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-2023-50447 2 Debian, Python 2 Debian Linux, Pillow 2024-03-27 N/A 8.1 HIGH
Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter).
CVE-2007-4559 1 Python 1 Python 2024-03-23 6.8 MEDIUM N/A
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-2023-44271 2 Fedoraproject, Python 2 Fedora, Pillow 2024-03-22 N/A 7.5 HIGH
An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
CVE-2022-22817 2 Debian, Python 2 Debian Linux, Pillow 2024-03-22 7.5 HIGH 9.8 CRITICAL
PIL.ImageMath.eval in Pillow before 9.0.0 allows evaluation of arbitrary expressions, such as ones that use the Python exec method. A lambda expression could also be used.
CVE-2021-23437 2 Fedoraproject, Python 2 Fedora, Pillow 2024-03-22 5.0 MEDIUM 7.5 HIGH
The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function.
CVE-2023-27043 1 Python 1 Python 2024-02-26 N/A 5.3 MEDIUM
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-2009-3720 4 A M Kuchling, Apache, Libexpat Project and 1 more 4 Pyxml, Http Server, Libexpat and 1 more 2024-02-22 5.0 MEDIUM N/A
The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
CVE-2020-27619 3 Fedoraproject, Oracle, Python 3 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python 2024-02-03 7.5 HIGH 9.8 CRITICAL
In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.
CVE-2023-43804 3 Debian, Fedoraproject, Python 3 Debian Linux, Fedora, Urllib3 2024-02-01 N/A 8.1 HIGH
urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5.
CVE-2021-28676 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-22 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load.
CVE-2022-48564 2 Netapp, Python 2 Active Iq Unified Manager, Python 2023-12-15 N/A 6.5 MEDIUM
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-2022-48560 2 Debian, Python 2 Debian Linux, Python 2023-12-10 N/A 7.5 HIGH
A use-after-free exists in Python through 3.9 via heappushpop in heapq.
CVE-2023-41105 2 Netapp, Python 2 Active Iq Unified Manager, Python 2023-12-10 N/A 7.5 HIGH
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.
