init_tmp in TeeJee.FileSystem.vala in Timeshift before 20.03 unsafely reuses a preexisting temporary directory in the predictable location /tmp/timeshift. It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.

A vulnerability in the filesystem of Cisco IOS XE Software could allow an authenticated, local attacker with physical access to an affected device to execute arbitrary code on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient file location validation. An attacker could exploit this vulnerability by placing code in a specific format on a USB device and inserting it into an affected Cisco device. A successful exploit could allow the attacker to execute the code with root privileges on the underlying OS of the affected device.

An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.
