Details:

USN-6513-1 fixed vulnerabilities in Python. This update provides the
corresponding updates for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and
Ubuntu 23.04.

Original advisory details:

  It was discovered that Python incorrectly handled certain plist files.
  If a user or an automated system were tricked into processing a specially
  crafted plist file, an attacker could possibly use this issue to consume
  resources, resulting in a denial of service. (CVE-2022-48564)

  It was discovered that Python instances of ssl.SSLSocket were vulnerable
  to a bypass of the TLS handshake. An attacker could possibly use this
  issue to cause applications to treat unauthenticated received data before
  TLS handshake as authenticated data after TLS handshake. (CVE-2023-40217)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.04:
   python3.11                      3.11.4-1~23.04.1
