30 Jan 2020 — 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. Python versiones 2.7 hasta 2.7.17, versiones 3.5 hasta 3.5.9, versiones 3.6 hasta 3.6.10, versiones 3.7 hasta 3.7.6 y versiones 3.8 hasta 3.8.1, permiten a un servidor HTTP conducir ataques de Denegación de Servicio de Expre... • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00003.html • CWE-400: Uncontrolled Resource Consumption •

Windows 8 and later are unaffected.

CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2019-18348 – python: CRLF injection via the host part of the url passed to urlopen()
https://notcve.org/view.php?id=CVE-2019-18348
23 Oct 2019 — 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.... • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00041.html • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

12 Oct 2019 — library/glob.html in the Python 2 and 3 documentation before 2016 has potentially misleading information about whether sorting occurs, as demonstrated by irreproducible cancer-research results. NOTE: the effects of this documentation cross application domains, and thus it is likely that security-relevant code elsewhere is affected. This issue is not a Python implementation bug, and there are no reports that NMR researchers were specifically relying on library/glob.html. In other words, because the older doc... • https://bugs.python.org/issue33275 • CWE-682: Incorrect Calculation •

https://notcve.org/view.php?id=CVE-2019-16935
28 Sep 2019 — The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server.

06 Sep 2019 — 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.

04 Sep 2019 — 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.

13 Jul 2019 — http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix (e.g., pythonicexample.com to steal cookies for example.com). When a program uses http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing cookies ca... • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00071.html • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2019-10160
07 Jun 2019 — 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 loca... • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00042.html • CWE-172: Encoding Error CWE-522: Insufficiently Protected Credentials •
