FreeBSD : openssh -- multiple vulnerabilities (2aedd15f-ca8b-11e6-a9a5-b499baebfeaf)

high Nessus Plugin ID 96116

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The OpenSSH project reports :

- ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside a trusted whitelist (run-time configurable). Requests to load modules could be passed via agent forwarding and an attacker could attempt to load a hostile PKCS#11 module across the forwarded agent channel: PKCS#11 modules are shared libraries, so this would result in code execution on the system running the ssh-agent if the attacker has control of the forwarded agent-socket (on the host running the sshd server) and the ability to write to the filesystem of the host running ssh-agent (usually the host running the ssh client). (CVE-2016-10009)

- sshd(8): When privilege separation is disabled, forwarded Unix-domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. This release refuses Unix-domain socket forwarding when privilege separation is disabled (Privilege separation has been enabled by default for 14 years).
CVE-2016-10010)

Solution

Update the affected package.
