Package        : libtirpc
CVE ID         : CVE-2021-46828
Debian Bug     : 1015873

It was discovered that libtirpc, a transport-independent RPC library,
does not properly handle idle TCP connections. A remote attacker can
take advantage of this flaw to cause a denial of service.

For the stable distribution (bullseye), this problem has been fixed in
version 1.3.1-1+deb11u1.

We recommend that you upgrade your libtirpc packages.

For the detailed security status of libtirpc please refer to
its security tracker page at:
