Releases

Packages

  • 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)
