It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-890 advisory.

    In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses     libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop     without accepting new connections. (CVE-2021-46828)

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5538-1 advisory.

    It was discovered that libtirpc incorrectly handled certain inputs. 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.
