The 'fusermount' binary, part of the FUSE system in Linux, executes the /bin/mount binary with ruid set to 0 without clearing the environment variables provided by unprivileged users.



This flaw can be leveraged by local unprivileged users to gain root privileges by leveraging the functionality provided by the LIBMOUNT_MTAB environment variable to overwrite an arbitrary file on the affected system.

This module exploits a command injection vulnerability in HP Client Automation. The flaw exists within the radexecd.exe component which listens by default on TCP port 3465. When handling a remote execution request the process does not properly authenticate the user issuing the request. The command to be executed is also not properly sanitized. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of SYSTEM.



Authentication is not required to exploit this vulnerability.
An elevation of privilege vulnerability exists when Windows kernel does not properly constrain impersonation levels.



The vulnerability occurs because a user can place symlinks for the system drives in the per-login session device map and the kernel will follow them during impersonation.



An attacker who successfully exploited this vulnerability may, for example, redirect a call to LoadLibrary, from a system service (when impersonating), to an arbitrary location.
