The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6858-1 advisory.
It was discovered that eSpeak NG did not properly manage memory under certain circumstances. An attacker could possibly use this issue to cause a denial of service, or execute arbitrary code. (CVE-2023-49990, CVE-2023-49991, CVE-2023-49992, CVE-2023-49993, CVE-2023-49994)
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.
