(1) core/tests/test_memmap.py, (2) core/tests/test_multiarray.py, (3) f2py/f2py2e.py, and (4) lib/tests/test_io.py in NumPy before 1.8.1 allow local users to write to arbitrary files via a symlink attack on a temporary file.

ROG Live Service’s function for deleting temp files created by installation has an improper link resolution before file access vulnerability. Since this function does not validate the path before deletion, an unauthenticated local attacker can create an unexpected symbolic link to system file path, to delete arbitrary system files and disrupt system service.

A vulnerability in the improper handling of symbolic links in Bitdefender Antivirus Free can allow an unprivileged user to substitute a quarantined file, and restore it to a privileged location. This issue affects Bitdefender Antivirus Free versions prior to 1.0.17.178.

<p>An elevation of privilege vulnerability exists when the OneDrive for Windows Desktop application improperly handles symbolic links. An attacker who successfully exploited this vulnerability could overwrite a targeted file with an elevated status.</p> <p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and delete a targeted file with an elevated status.</p> <p>The update addresses this vulnerability by correcting where the OneDrive updater performs file writes while running with elevation.</p>

IOBit Advanced SystemCare Free 13.5.0.263 allows local users to gain privileges for file deletion by manipulating the Clean & Optimize feature with an NTFS junction and an Object Manager symbolic link.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 is affected. The issue involves symlink mishandling in the "libarchive" component. It allows local users to change arbitrary directory permissions via unspecified vectors.

OpenVPN Connect installer for macOS version 3.2.6 and older may corrupt system critical files it should not have access via symlinks in /tmp.

A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal.

as31 2.3.1-4 does not seed the random number generator and generates predictable temporary file names, which makes it easier for local users to create or truncate files via a symlink attack.

An improper link resolution before file access vulnerability exists in the Palo Alto Networks Cortex XDR agent on Windows platforms that enables a local user to delete arbitrary system files and impact the system integrity or cause a denial of service condition. This issue impacts: Cortex XDR agent 5.0 versions earlier than Cortex XDR agent 5.0.12; Cortex XDR agent 6.1 versions earlier than Cortex XDR agent 6.1.9; Cortex XDR agent 7.2 versions earlier than Cortex XDR agent 7.2.4; Cortex XDR agent 7.3 versions earlier than Cortex XDR agent 7.3.2.

ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user.

An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks, aka 'Windows User Profile Service Elevation of Privilege Vulnerability'.

keycloak-httpd-client-install versions before 0.8 insecurely creates temporary file allowing local attackers to overwrite other files via symbolic link.

GNU Parallel before 20150522 (Nepal), when using (1) --cat or (2) --fifo with --sshlogin, allows local users to write to arbitrary files via a symlink attack on a temporary file.

In WIBU CodeMeter Runtime before 7.30a, creating a crafted CmDongles symbolic link will overwrite the linked file without checking permissions.

NVIDIA GPU Display driver for Windows contains a vulnerability where an unprivileged user can create a file hard link that causes the driver to overwrite a file that requires elevated privilege to modify, which could lead to data loss or denial of service.

A validation issue existed in the handling of symlinks. This issue was addressed with improved validation of symlinks. This issue is fixed in macOS Catalina 10.15.3. A malicious application may be able to overwrite arbitrary files.

A flaw was found in katello-debug before 3.4.0 where certain scripts and log files used insecure temporary files. A local user could exploit this flaw to conduct a symbolic-link attack, allowing them to overwrite the contents of arbitrary files.
