How to fix?
Upgrade Debian:11 libtirpc to version 1.3.1-1+deb11u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libtirpc package and not the libtirpc package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
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.
