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.

(1) contrib/gforge-3.0-cronjobs.patch, (2) cronjobs/homedirs.php, (3) deb-specific/fileforge.pl, (4) deb-specific/group_dump_update.pl, (5) deb-specific/ssh_dump_update.pl, (6) deb-specific/user_dump_update.pl, (7) plugins/scmbzr/common/BzrPlugin.class.php, (8) plugins/scmcvs/common/CVSPlugin.class.php, (9) plugins/scmcvs/cronjobs/cvs.php, (10) plugins/scmcvs/cronjobs/ssh_create.php, (11) plugins/scmgit/common/GitPlugin.class.php, (12) plugins/scmsvn/common/SVNPlugin.class.php, (13) plugins/wiki/cronjobs/create_groups.php, (14) utils/cvs1/cvscreate.sh, and (15) utils/include.pl in FusionForge 5.0, 5.1, and 5.2 allows local users to change arbitrary file permissions, obtain sensitive information, and have other unspecified impacts via a (1) symlink or (2) hard link attack on certain files.

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.

Trendnet AC2600 TEW-827DRU version 2.08B01 contains a symlink vulnerability in the bittorrent functionality. If enabled, the bittorrent functionality is vulnerable to a symlink attack that could lead to remote code execution on the device. If an end user inserts a flash drive with a malicious symlink on it that the bittorrent client can write downloads to, then a user is able to download arbitrary files to any desired location on the devices filesystem, which could lead to remote code execution. Example directories vulnerable to this include "config", "downloads", and "torrents", though it should be noted that "downloads" is the only vector that allows for arbitrary files to be downloaded to arbitrary locations.

The (1) shell_exec function in lib/util/MiqSshUtilV1.rb and (2) temp_cmd_file function in lib/util/MiqSshUtilV2.rb in Red Hat CloudForms 3.0 Management Engine (CFME) before 5.2.4.2 allow local users to execute arbitrary commands via a symlink attack on a temporary file with a predictable name.

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. 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.

The init script in the Debian x11-common package before 1:7.6+12 is vulnerable to a symlink attack that can lead to a privilege escalation during package installation.

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.
