Microsoft Office Click-To-Run Elevation of Privilege Vulnerability

Windows Search Service Elevation of Privilege Vulnerability

cfgcon in IBM AIX 5.2 and 5.3 does not properly validate the argument to the "-p" option to swcons, which allows local users in the system group to create an arbitrary file, and enable world writability of this file, via a symlink attack involving use of the file's name as the argument.

Windows Installer Elevation of Privilege Vulnerability

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.
