CVE-2021-46828

HIGH

libtirpc <1.3.3rc1 - DoS

Title source: llm

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.
