Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4481-1 advisory.

 It was discovered that FreeRDP incorrectly handled certain memory operations. A remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly execute arbitrary code.
