CVE-2016-10009
Description
It was found that ssh-agent could load PKCS#11 modules from arbitrary paths. An attacker having control of the forwarded agent-socket on the server, and the ability to write to the filesystem of the client host, could use this flaw to execute arbitrary code with the privileges of the user running ssh-agent.
Statement
In order to exploit this flaw, the attacker needs to have control of the forwarded agent-socket and the ability to write to the filesystem of the host running ssh-agent. Because of this restriction for successful exploitation, this issue has been rated as having Moderate security impact. A future update may address this flaw.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
