Descriptions

An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities.

A flaw was found in Python caused by improper handling of XML external entity (XXE) declarations by the plistlib module. By using a specially crafted XML content, an attacker could obtain sensitive information by disclosing files specified by parsing URI, and may cause denial of service by resource exhaustion.

It was discovered that Python incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 18.04 LTS. It was discovered that Python incorrectly used regular expressions vulnerable to catastrophic backtracking. A remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS.
