CVE-2017-8779 Open this link in a new tabHow to fix?
Upgrade Debian:unstable libtirpc to version 0.2.5-1.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libtirpc package and not the libtirpc package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc through 1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC data size during memory allocation for XDR strings, which allows remote attackers to cause a denial of service (memory consumption with no subsequent free) via a crafted UDP packet to port 111, aka rpcbomb.
