Summary

libtirpc security update

Details

Libtirpc is a Transport-Independent RPC library for Linux

Security Fix(es):

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)

Severity

7.5 (High)
