"It was discovered that libtiprc, a transport-independent RPC library,
could be used for a denial of service or possibly unspecified other
impact by a stack-based buffer overflow due to a flood of crafted ICMP
and UDP packets.

For Debian 8 'Jessie', this problem has been fixed in version
0.2.5-1+deb8u3.

We recommend that you upgrade your libtirpc packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
