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.
Affected configurations
• libtirpc project libtirpc (< 1.3.3)
• debian debian linux 10.0
• debian debian linux 11.0
