CVE-2021-29921 3 Oracle, Python, Redhat 8 Communications Cloud Native Core Automated Test Suite, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Slice Selection Function and 5 more 2025-11-03 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 7 Fedora, Python, Enterprise Linux and 4 more 2025-11-03 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 4 Fedoraproject, Netapp, Python and 1 more 7 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 4 more 2025-11-03 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-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-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-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-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-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-2017-1000158 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-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-2017-20052 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-2016-5699 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-2016-5636 2 Python, Redhat 2 Python, Enterprise Linux 2025-04-12 N/A
Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.
CVE-2013-7040 2 Apple, Python 2 Mac Os X, Python 2025-04-12 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-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-2016-2533 3 Debian, Python, Python Imaging Project 3 Debian Linux, Pillow, Python Imaging 2025-04-12 N/A
Buffer overflow in the ImagingPcdDecode function in PcdDecode.c in Pillow before 3.1.1 and Python Imaging Library (PIL) 1.1.7 and earlier allows remote attackers to cause a denial of service (crash) via a crafted PhotoCD file.
CVE-2013-7338 2 Apple, Python 2 Mac Os X, Python 2025-04-12 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.
