USN-6354-1: Python vulnerability
7 September 2023
Python could be made to crash or leak sensitive information if it received specially crafted input.
Releases
Packages
- python2.7 - An interactive high-level object-oriented language
- python3.5 - An interactive high-level object-oriented language
Details
It was discovered that Python did not properly handle XML entity
declarations in plist files. An attacker could possibly use this
vulnerability to perform an XML External Entity (XXE) injection,
resulting in a denial of service or information disclosure.
