CVE-2019-9948 – python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms
https://notcve.org/view.php?id=CVE-2019-9948
23 Mar 2019 — 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. urllib en Python, en versiones 2.x hasta la 2.7.16, soporta el esquema local_file:, lo que facilita que los atacantes remotos omitan los mecanismos de protección que ponen en lista negra los URI file:, tal y como queda demostrado con una llamada urllib.urlopen... • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-749: Exposed Dangerous Method or Function •

CVE-2019-9740 – python: CRLF injection via the query part of the url passed to urlopen()
https://notcve.org/view.php?id=CVE-2019-9740
13 Mar 2019 — 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... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00039.html • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

https://notcve.org/view.php?id=CVE-2018-1000030
08 Feb 2018 — Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer ... • https://github.com/tylepr96/CVE-2018-1000030 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
