| CVE-2022-42919 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Python, Enterprise Linux and 1 more | 2025-05-02 | 7.8 High |
| Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do that in CPython before 3.9. | ||||
| CVE-2022-45061 | 4 Fedoraproject, Netapp, Python and 1 more | 13 Fedora, Active Iq Unified Manager, Bootstrap Os and 10 more | 2025-05-01 | 7.5 High |
| 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-2024-9287 | 2 Python, Redhat | 4 Cpython, Python, Enterprise Linux and 1 more | 2025-04-25 | 7.8 High |
| A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/bin/activate"). This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected. | ||||
| 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-2016-6580 | 1 Python | 1 Python Priority Library | 2025-04-20 | N/A |
| A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0 could be targeted by a malicious peer by having that peer assign priority information for every possible HTTP/2 stream ID. The priority tree would happily continue to store the priority information for each stream, and would therefore allocate unbounded amounts of memory. Attempting to actually use a tree like this would also cause extremely high CPU usage to maintain the tree. | ||||
| CVE-2017-5992 | 1 Python | 1 Openpyxl | 2025-04-20 | N/A |
| Openpyxl 2.4.1 resolves external entities by default, which allows remote attackers to conduct XXE attacks via a crafted .xlsx document. | ||||
| CVE-2016-6581 | 1 Python | 2 Hpack, Hyper | 2025-04-20 | N/A |
| A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK dynamic header table into the dynamic header table. The attacker can then send a header block that is simply repeated requests to expand that field in the dynamic table. This can lead to a gigantic compression ratio of 4,096 or better, meaning that 16kB of data can decompress to 64MB of data on the target machine. | ||||
| CVE-2017-9233 | 3 Debian, Libexpat Project, Python | 3 Debian Linux, Libexpat, Python | 2025-04-20 | 7.5 High |
| XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD. | ||||
| CVE-2016-3076 | 1 Python | 1 Pillow | 2025-04-20 | N/A |
| Heap-based buffer overflow in the j2k_encode_entry function in Pillow 2.5.0 through 3.1.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted Jpeg2000 file. | ||||
| CVE-2017-2810 | 1 Python | 1 Tablib | 2025-04-20 | N/A |
| An exploitable vulnerability exists in the Databook loading functionality of Tablib 0.11.4. A yaml loaded Databook can execute arbitrary python commands resulting in command execution. An attacker can insert python into loaded yaml to trigger this vulnerability. | ||||
| CVE-2017-1000158 | 2 Debian, Python | 2 Debian Linux, Python | 2025-04-20 | 9.8 Critical |
| 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-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. | ||||
| CVE-2014-4616 | 5 Opensuse, Opensuse Project, Python and 2 more | 8 Opensuse, Opensuse, Python and 5 more | 2025-04-20 | 5.9 Medium |
| Array index error in the scanstring function in the _json module in Python 2.7 through 3.5 and simplejson before 2.6.1 allows context-dependent attackers to read arbitrary process memory via a negative index value in the idx argument to the raw_decode function. | ||||
| CVE-2017-17522 | 1 Python | 1 Python | 2025-04-20 | N/A |
| 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-2017-20052 | 1 Python | 1 Python | 2025-04-15 | 5 Medium |
| A vulnerability classified as problematic was found in Python 2.7.13. This vulnerability affects unknown code of the component pgAdmin4. The manipulation leads to uncontrolled search path. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. | ||||
| CVE-2016-0718 | 10 Apple, Canonical, Debian and 7 more | 16 Mac Os X, Ubuntu Linux, Debian Linux and 13 more | 2025-04-12 | 9.8 Critical |
| Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. | ||||
| CVE-2014-0224 | 9 Fedoraproject, Filezilla-project, Mariadb and 6 more | 23 Fedora, Filezilla Server, Mariadb and 20 more | 2025-04-12 | 7.4 High |
| OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability. | ||||
| CVE-2014-1932 | 2 Python, Pythonware | 2 Pillow, Python Imaging Library | 2025-04-12 | N/A |
| The (1) load_djpeg function in JpegImagePlugin.py, (2) Ghostscript function in EpsImagePlugin.py, (3) load function in IptcImagePlugin.py, and (4) _copy function in Image.py in Python Image Library (PIL) 1.1.7 and earlier and Pillow before 2.3.1 do not properly create temporary files, which allow local users to overwrite arbitrary files and obtain sensitive information via a symlink attack on the temporary file. | ||||
| CVE-2015-1283 | 9 Canonical, Debian, Google and 6 more | 14 Ubuntu Linux, Debian Linux, Chrome and 11 more | 2025-04-12 | N/A |
| Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716. | ||||
| CVE-2014-9601 | 4 Fedoraproject, Opensuse, Oracle and 1 more | 4 Fedora, Opensuse, Solaris and 1 more | 2025-04-12 | N/A |
| Pillow before 2.7.0 allows remote attackers to cause a denial of service via a compressed text chunk in a PNG image that has a large size when it is decompressed. | ||||
