| CVE-2025-6069 | 1 Python | 1 Cpython | 2025-10-09 | 4.3 Medium |
| The html.parser.HTMLParser class had worse-case quadratic complexity when processing certain crafted malformed inputs potentially leading to amplified denial-of-service. | ||||
| CVE-2024-5642 | 1 Python | 1 Cpython | 2025-10-09 | 6.5 Medium |
| CPython 3.9 and earlier doesn't disallow configuring an empty list ("[]") for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured). | ||||
| CVE-2025-50817 | 1 Python | 1 Python | 2025-09-26 | 5.4 Medium |
| A vulnerability in the Python-Future 1.0.0 module allows for arbitrary code execution via the unintended import of a file named test.py. When the module is loaded, it automatically imports test.py, if present in the same directory or in the sys.path. This behavior can be exploited by an attacker who has the ability to write files to the server, allowing the execution of arbitrary code. NOTE: Multiple third parties have disputed this issue and stated that it is not a security flaw in python-future and is a documented feature of Python’s import system in the handling of sys.path. | ||||
| CVE-2025-50181 | 2 Python, Urllib3 | 2 Urllib3, Urllib3 | 2025-09-18 | 5.3 Medium |
| urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable redirects. By default, requests and botocore users are not affected. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0. | ||||
| CVE-2018-25032 | 13 Apple, Azul, Debian and 10 more | 47 Mac Os X, Macos, Zulu and 44 more | 2025-08-21 | 7.5 High |
| zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. | ||||
| CVE-2021-27923 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Pillow, Enterprise Linux and 1 more | 2025-08-15 | 7.5 High |
| Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICO container, and thus an attempted memory allocation can be very large. | ||||
| CVE-2021-27922 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Pillow, Enterprise Linux and 1 more | 2025-08-15 | 7.5 High |
| Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large. | ||||
| CVE-2021-27921 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Pillow, Enterprise Linux and 1 more | 2025-08-15 | 7.5 High |
| Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for a BLP container, and thus an attempted memory allocation can be very large. | ||||
| CVE-2024-12718 | 2 Python, Redhat | 7 Cpython, Enterprise Linux, Rhel Aus and 4 more | 2025-07-24 | 5.3 Medium |
| Allows modifying some file metadata (e.g. last modified) with filter="data" or file permissions (chmod) with filter="tar" of files outside the extraction directory. You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the filter= parameter with a value of "data" or "tar". See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information. Only Python versions 3.12 or later are affected by these vulnerabilities, earlier versions don't include the extraction filter feature. Note that for Python 3.14 or later the default value of filter= changed from "no filtering" to `"data", so if you are relying on this new default behavior then your usage is also affected. Note that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links. | ||||
| CVE-2024-3220 | 1 Python | 1 Cpython | 2025-07-13 | 4.6 Medium |
| There is a defect in the CPython standard library module “mimetypes” where on Windows the default list of known file locations are writable meaning other users can create invalid files to cause MemoryError to be raised on Python runtime startup or have file extensions be interpreted as the incorrect file type. This defect is caused by the default locations of Linux and macOS platforms (such as “/etc/mime.types”) also being used on Windows, where they are user-writable locations (“C:\etc\mime.types”). To work-around this issue a user can call mimetypes.init() with an empty list (“[]”) on Windows platforms to avoid using the default list of known file locations. | ||||
| CVE-2024-4030 | 1 Python | 1 Cpython | 2025-07-12 | 7.1 High |
| On Windows a directory returned by tempfile.mkdtemp() would not always have permissions set to restrict reading and writing to the temporary directory by other users, instead usually inheriting the correct permissions from the default location. Alternate configurations or users without a profile directory may not have the intended permissions. If you’re not using Windows or haven’t changed the temporary directory location then you aren’t affected by this vulnerability. On other platforms the returned directory is consistently readable and writable only by the current user. This issue was caused by Python not supporting Unix permissions on Windows. The fix adds support for Unix “700” for the mkdir function on Windows which is used by mkdtemp() to ensure the newly created directory has the proper permissions. | ||||
| CVE-2025-4435 | 2 Python, Redhat | 7 Cpython, Enterprise Linux, Rhel Aus and 4 more | 2025-07-07 | 7.5 High |
| When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member would still be extracted and not skipped. | ||||
| CVE-2025-4516 | 1 Python | 1 Cpython | 2025-06-24 | 5.1 Medium |
| There is an issue in CPython when using `bytes.decode("unicode_escape", error="ignore|replace")`. If you are not using the "unicode_escape" encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError. | ||||
| CVE-2025-47273 | 3 Debian, Python, Redhat | 4 Debian Linux, Setuptools, Enterprise Linux and 1 more | 2025-06-12 | 8.8 High |
| setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version 78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the permissions of the process running the Python code, which could escalate to remote code execution depending on the context. Version 78.1.1 fixes the issue. | ||||
| CVE-2019-12900 | 7 Bzip, Canonical, Debian and 4 more | 9 Bzip2, Ubuntu Linux, Debian Linux and 6 more | 2025-06-09 | 9.8 Critical |
| BZ2_decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors. | ||||
| CVE-2016-3189 | 2 Bzip, Python | 2 Bzip2, Python | 2025-06-09 | 6.5 Medium |
| Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start of the block. | ||||
| CVE-2019-15903 | 3 Libexpat Project, Python, Redhat | 5 Libexpat, Python, Enterprise Linux and 2 more | 2025-05-30 | 6.5 Medium |
| In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. | ||||
| CVE-2022-37454 | 9 Debian, Extended Keccak Code Package Project, Fedoraproject and 6 more | 9 Debian Linux, Extended Keccak Code Package, Fedora and 6 more | 2025-05-08 | 9.8 Critical |
| The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface. | ||||
| CVE-2022-24902 | 1 Python | 1 Tkvideoplayer | 2025-04-23 | 2.9 Low |
| TkVideoplayer is a simple library to play video files in tkinter. Uncontrolled memory consumption in versions of TKVideoplayer prior to 2.0.0 can theoretically lead to performance degradation. There are no known workarounds. This issue has been patched and users are advised to upgrade to version 2.0.0 or later. | ||||
| CVE-2016-9015 | 1 Python | 1 Urllib3 | 2025-04-20 | N/A |
| Versions 1.17 and 1.18 of the Python urllib3 library suffer from a vulnerability that can cause them, in certain configurations, to not correctly validate TLS certificates. This places users of the library with those configurations at risk of man-in-the-middle and information leakage attacks. This vulnerability affects users using versions 1.17 and 1.18 of the urllib3 library, who are using the optional PyOpenSSL support for TLS instead of the regular standard library TLS backend, and who are using OpenSSL 1.1.0 via PyOpenSSL. This is an extremely uncommon configuration, so the security impact of this vulnerability is low. | ||||
