Software Description:

Details:

USN-7280-2 fixed vulnerabilities in Python. It was discovered that the
fixes for CVE-2025-0938 and CVE-2024-11168 were incorrectly applied on
Ubuntu 14.04 LTS as a result. This update fixes the problem.

 included square brackets. A remote attacker could possibly use this issue
 to perform a Server-Side Request Forgery (SSRF) attack.

package versions:

Ubuntu 14.04 LTS
  libpython2.7                    2.7.6-8ubuntu0.6+esm28
