FKIE_CVE-2017-8779
Vulnerability from fkie_nvd - Published: 2017-05-04 14:29 - Updated: 2026-06-17 01:26
Severity
Summary
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.
