Vulnerability Name:

CVE-2021-46828 (CCN-232191)

Assigned:2021-08-21
Published:2021-08-21
Updated:2022-12-02
Summary: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.
