| 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-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-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-2016-3189 | 2 Bzip, Python | 2 Bzip2, Python | 2025-04-12 | 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-2016-0772 | 2 Python, Redhat | 3 Python, Enterprise Linux, Rhel Software Collections | 2025-04-12 | N/A |
| The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack." | ||||
| CVE-2015-5652 | 2 Microsoft, Python | 2 Windows, Python | 2025-04-12 | N/A |
| Untrusted search path vulnerability in python.exe in Python through 3.5.0 on Windows allows local users to gain privileges via a Trojan horse readline.pyd file in the current working directory. NOTE: the vendor says "It was determined that this is a longtime behavior of Python that cannot really be altered at this point." | ||||
| CVE-2016-4472 | 4 Canonical, Libexpat Project, Mcafee and 1 more | 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more | 2025-04-12 | 8.1 High |
| The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716. | ||||
| CVE-2016-5699 | 2 Python, Redhat | 3 Python, Enterprise Linux, Rhel Software Collections | 2025-04-12 | N/A |
| CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython (aka Python) before 2.7.10 and 3.x before 3.4.4 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL. | ||||
| 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-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-2014-9365 | 3 Apple, Python, Redhat | 4 Mac Os X, Python, Enterprise Linux and 1 more | 2025-04-12 | N/A |
