The remote Ubuntu 24.04 LTS. host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6759-1 advisory.
It was discovered that FreeRDP incorrectly handled certain memory operations. If a user were tricked into connecting to a malicious server, a remote attacker could possibly use this issue to cause FreeRDP to crash, resulting in a denial of service.
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
