Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:8400 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)
