| CVE-2020-14422 | 5 Fedoraproject, Opensuse, Oracle and 2 more | 6 Fedora, Leap, Enterprise Manager Ops Center and 3 more | 2026-10-14 | 5.9 Medium |
| Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2. | ||||
| CVE-2020-8492 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2026-10-14 | 6.5 Medium |
| Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking. | ||||
| CVE-2020-8315 | 1 Python | 1 Python | 2026-10-14 | 5.5 Medium |
| In Python (CPython) 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1, an insecure dependency load upon launch on Windows 7 may result in an attacker's copy of api-ms-win-core-path-l1-1-0.dll being loaded and used instead of the system's copy. Windows 8 and later are unaffected. | ||||
| CVE-2020-10735 | 3 Fedoraproject, Python, Redhat | 7 Fedora, Python, Enterprise Linux and 4 more | 2026-10-14 | 6.2 Medium |
| 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-2019-20907 | 8 Canonical, Debian, Fedoraproject and 5 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2026-10-14 | 5.5 Medium |
| In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation. | ||||
| CVE-2019-9948 | 6 Canonical, Debian, Fedoraproject and 3 more | 18 Ubuntu Linux, Debian Linux, Fedora and 15 more | 2026-10-14 | 9.1 Critical |
| urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call. | ||||
| CVE-2019-9947 | 2 Python, Redhat | 8 Python, Ansible Tower, Enterprise Linux and 5 more | 2026-10-14 | 5.4 Medium |
| An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character) followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. | ||||
| CVE-2019-9740 | 2 Python, Redhat | 8 Python, Ansible Tower, Enterprise Linux and 5 more | 2026-10-14 | 6.5 Medium |
| An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the query string after a ? character) followed by an HTTP header or a Redis command. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. | ||||
| CVE-2019-9674 | 3 Canonical, Netapp, Python | 3 Ubuntu Linux, Active Iq Unified Manager, Python | 2026-10-14 | 7.5 High |
| Lib/zipfile.py in Python through 3.7.2 allows remote attackers to cause a denial of service (resource consumption) via a ZIP bomb. | ||||
| CVE-2019-9636 | 7 Canonical, Debian, Fedoraproject and 4 more | 21 Ubuntu Linux, Debian Linux, Fedora and 18 more | 2026-10-14 | 5.3 Medium |
| Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. | ||||
| CVE-2019-18348 | 2 Python, Redhat | 2 Python, Rhel Software Collections | 2026-10-14 | 5.4 Medium |
| An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header. This is similar to the CVE-2019-9740 query string issue and the CVE-2019-9947 path string issue. (This is not exploitable when glibc has CVE-2016-10739 fixed.). This is fixed in: v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1; v3.6.11, v3.6.11rc1, v3.6.12; v3.7.8, v3.7.8rc1, v3.7.9; v3.8.3, v3.8.3rc1, v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1. | ||||
| CVE-2019-16056 | 7 Canonical, Debian, Fedoraproject and 4 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2026-10-14 | 5.3 Medium |
| An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally. | ||||
| CVE-2019-15903 | 3 Libexpat Project, Python, Redhat | 5 Libexpat, Python, Enterprise Linux and 2 more | 2026-10-14 | 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-2019-12900 | 7 Bzip, Canonical, Debian and 4 more | 9 Bzip2, Ubuntu Linux, Debian Linux and 6 more | 2026-10-14 | 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-2019-10160 | 7 Canonical, Debian, Fedoraproject and 4 more | 16 Ubuntu Linux, Debian Linux, Fedora and 13 more | 2026-10-14 | 9.8 Critical |
| A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application. | ||||
| CVE-2016-3189 | 2 Bzip, Python | 2 Bzip2, Python | 2026-10-14 | 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-2015-20107 | 4 Fedoraproject, Netapp, Python and 1 more | 7 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 4 more | 2026-10-14 | 7.8 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-2013-0340 | 3 Apple, Libexpat Project, Python | 7 Ipados, Iphone Os, Macos and 4 more | 2026-10-14 | N/A |
| expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. | ||||
| 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 | 2026-10-09 | 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-2020-27619 | 4 Fedoraproject, Oracle, Python and 1 more | 5 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python and 2 more | 2026-10-09 | 9.8 Critical |
| In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP. | ||||
