| CVE-2022-42919 | 2 Fedoraproject, Python | 2 Fedora, Python | 2025-11-03 | N/A | 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-2021-3733 | 4 Fedoraproject, Netapp, Python and 1 more | 20 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 17 more | 2025-11-03 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2021-29921 | 2 Oracle, Python | 6 Communications Cloud Native Core Automated Test Suite, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Slice Selection Function and 3 more | 2025-11-03 | 7.5 HIGH | 9.8 CRITICAL |
| In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses. | |||||
| CVE-2020-10735 | 3 Fedoraproject, Python, Redhat | 5 Fedora, Python, Enterprise Linux and 2 more | 2025-11-03 | N/A | 7.5 HIGH |
| 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-2015-20107 | 3 Fedoraproject, Netapp, Python | 5 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 2 more | 2025-11-03 | 8.0 HIGH | 7.6 HIGH |
| In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 | |||||

| CVE-2016-3189 | 2 Bzip, Python | 2 Bzip2, Python | 2025-06-09 | 4.3 MEDIUM | 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 | 2 Libexpat Project, Python | 2 Libexpat, Python | 2025-05-30 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 8 Debian, Extended Keccak Code Package Project, Fedoraproject and 5 more | 8 Debian Linux, Extended Keccak Code Package, Fedora and 5 more | 2025-05-08 | N/A | 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-2017-17522 | 1 Python | 1 Python | 2025-04-20 | 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 | |||||

| 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-2017-1000158 | 2 Debian, Python | 2 Debian Linux, Python | 2025-04-20 | 7.5 HIGH | 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-2017-9233 | 3 Debian, Libexpat Project, Python | 3 Debian Linux, Libexpat, Python | 2025-04-20 | 5.0 MEDIUM | 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-2016-5699 | 1 Python | 1 Python | 2025-04-12 | 4.3 MEDIUM | 6.1 MEDIUM |
| 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-2014-7185 | 2 Apple, Python | 2 Mac Os X, Python | 2025-04-12 | 6.4 MEDIUM | N/A |
| Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function. | |||||
| CVE-2016-2183 | 6 Cisco, Nodejs, Openssl and 3 more | 9 Content Security Management Appliance, Node.js, Openssl and 6 more | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
| The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack. | |||||
| CVE-2013-7338 | 2 Apple, Python | 2 Mac Os X, Python | 2025-04-12 | 7.1 HIGH | N/A |
| Python before 3.3.4 RC1 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a file size value larger than the size of the zip file to the (1) ZipExtFile.read, (2) ZipExtFile.read(n), (3) ZipExtFile.readlines, (4) ZipFile.extract, or (5) ZipFile.extractall function. | |||||
| CVE-2013-7040 | 2 Apple, Python | 2 Mac Os X, Python | 2025-04-12 | 4.3 MEDIUM | N/A |
| Python 2.7 before 3.4 only uses the last eight bits of the prefix to randomize hash values, which causes it to compute hash values without restricting the ability to trigger hash collisions predictably and makes it easier for context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1150. | |||||
| CVE-2013-7440 | 1 Python | 1 Python | 2025-04-12 | 4.3 MEDIUM | 5.9 MEDIUM |
| The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate. | |||||
