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. NOTE: this issue is due to an incomplete fix for CVE-2007-5804.

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.

mysqld_safe in Oracle MySQL through 5.5.51, 5.6.x through 5.6.32, and 5.7.x through 5.7.14; MariaDB; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17, when using file-based logging, allows local users with access to the mysql account to gain root privileges via a symlink attack on error logs and possibly other files.

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.

NVIDIA GeForce Experience before 3.18 contains a vulnerability when ShadowPlay or GameStream is enabled. When an attacker has access to the system and creates a hard link, the software does not check for hard link attacks. This behavior may lead to code execution, denial of service, or escalation of privileges.

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. This issue affects: SUSE Linux Enterprise Server 12 nagios version 3.5.1-5.27 and prior versions.

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.
