CVE-2021-46828 HIGH

Published: 2022-07-20 | Last Modified: 2025-05-05 | Status: Modified

Description

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.

Additional Descriptions (1)

En libtirpc versiones anteriores a 1.3.3rc1, los atacantes remotos podían agotar los descriptores de archivo de un proceso que usa libtirpc porque las conexiones TCP inactivas son manejadas inapropiadamente. Esto puede, a su vez, conllevar a un bucle infinito svc_run sin aceptar nuevas conexiones
