libodm.a in IBM AIX 6.1 and 7.1, and VIOS 2.2.x, allows local users to overwrite arbitrary files via a symlink attack on a temporary file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2179.

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.

The LHA.sys driver before 1.1.1811.2101 in LG Device Manager exposes functionality that allows low-privileged users to read and write arbitrary physical memory via specially crafted IOCTL requests and elevate system privileges. This occurs because the device object has an associated symbolic link and an open DACL.

UNIX Symbolic Link (Symlink) Following vulnerability in the cronjob shipped with nagios of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 11; openSUSE Factory allows local attackers to cause cause DoS or potentially escalate privileges by winning a race.

SUSE Linux Enterprise Server 11 nagios version 3.0.6-1.25.36.3.1 and prior versions. openSUSE Factory nagios version 4.4.5-2.1 and prior versions.

deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/<block-dev-basename> in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. 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.
