Vulnerability from github – Published: 2022-07-21 00:00 – Updated: 2026-10-14 15:31

Details

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.

Severity

7.5 (High)
