Description

The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-8380-1 advisory.

 It was discovered that Twisted incorrectly handled DNS name decompression. A remote attacker could possibly use this issue to cause Twisted to consume excessive resources, leading to a denial of service.
