python2.7, python3.5 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Python.

Software Description:
- python2.7: An interactive high-level object-oriented language
- python3.5: An interactive high-level object-oriented language

Details:

USN-7015-1 fixed several vulnerabilities in Python. This update provides
one of the corresponding updates for python2.7 for Ubuntu 16.04 LTS,
Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS, and a second for
python3.5 for Ubuntu 16.04 LTS.

Original advisory details:

  It was discovered that Python allowed excessive backtracking while
  parsing certain tarfile headers. A remote attacker could possibly use
  this issue to cause Python to consume resources, leading to a denial
  of service. This issue only affected python3.5 for
  Ubuntu 16.04 LTS (CVE-2024-6232)

  It was discovered that the Python http.cookies module incorrectly
  handled parsing cookies that contained backslashes for quoted
  characters. A remote attacker could possibly use this issue to
  cause Python to consume resources, leading to a denial
  of service. (CVE-2024-7592)
