A vulnerability classified as problematic has been found in Joyent SmartOS 20161110T013148Z (Operating System). This affects an unknown code of the component Hyprlofs File System. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:
An exploitable denial of service exists in the the Joyent SmartOS 20161110T013148Z Hyprlofs file system. The vulnerability is present in the Ioctl system call with the command HYPRLOFS_ADD_ENTRIES. An attacker can cause a buffer to be allocated and never freed. When repeatedly exploited this will result in memory exhaustion, resulting in a full system denial of service.
