CVE-2017-8779
7.5 · HIGHOverview
CVE-2017-8779 is a high-severity vulnerability affecting rpcbind_project rpcbind. It was published on May 4, 2017 and has a CVSS 3.0 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from rpcbind_project. Update rpcbind to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
