CVE-2019-9636 – python: Information Disclosure due to urlsplit improper NFKC normalization
https://notcve.org/view.php?id=CVE-2019-9636
08 Mar 2019 — 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 c... • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html • CWE-172: Encoding Error •

CVE-2018-20406 – python: Integer overflow in Modules/_pickle.c allows for memory exhaustion if serializing gigabytes of data
https://notcve.org/view.php?id=CVE-2018-20406
23 Dec 2018 — Modules/_pickle.c in Python before 3.7.1 has an integer overflow via a large LONG_BINPUT value that is mishandled during a "resize to twice the size" attempt. This issue might cause memory exhaustion, but is only relevant if the pickle format is used for serializing tens or hundreds of gigabytes of data. This issue is fixed in: v3.4.10, v3.4.10rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.7rc1, 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, v3.6.7, v3.6.7rc1, v3.6.7rc2, v3... • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
