Synopsis

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6780-1 advisory.

 Guido Vranken discovered that idna did not properly manage certain inputs,

 which could lead to significant resource consumption. An attacker could

 possibly use this issue to cause a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
