Summary
Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing.
Security Fix(es):
* numpy: crafted serialized object passed in numpy.load() in pickle python module allows arbitrary code execution (CVE-2019-6446)
* python: CRLF injection via the query part of the url passed to urlopen() (CVE-2019-9740)
* python: CRLF injection via the path part of the url passed to urlopen() (CVE-2019-9947)
* python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms (CVE-2019-9948)
* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)
* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)

Vulnerabilities 6
-
Critical 9.8
Numpy Deserialization of Untrusted Data
An issue was discovered in NumPy before 1.16.3. It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call. NOTE: third parties dispute this issue be…

High 7.5
Improper Certificate Validation in urllib3
The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the cor…
