A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of exim in openSUSE Factory allows local attackers to escalate from user mail to root. This issue affects: openSUSE Factory exim versions prior to 4.93.0.4-3.1.

Exim 4 before 4.94.2 allows Heap-based Buffer Overflow because it mishandles "-F '.('" on the command line, and thus may allow privilege escalation from any user to root. This occurs because of the interpretation of negative sizes in strncpy.

Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. Local users can alter the behavior of root processes because a recipient address can have a newline character.

Exim 4 before 4.94.2 allows Heap-based Buffer Overflow in queue_run via two sender options: -R and -S. This may cause privilege escalation from exim to root.

Exim 4 before 4.94.2 allows Out-of-bounds Write because the main function, while setuid root, copies the current working directory pathname into a buffer that is too small (on some common platforms).

Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because get_stdinput allows unbounded reads that are accompanied by unbounded increases in a certain size variable. NOTE: exploitation may be impractical because of the execution time needed to overflow (multiple days).

Exim 4 before 4.94.2 allows Exposure of File Descriptor to Unintended Control Sphere because rda_interpret uses a privileged pipe that lacks a close-on-exec flag.

Exim 4 before 4.94.2 allows an off-by-two Out-of-bounds Write because "-F ''" is mishandled by parse_fix_phrase.

A use-after-free in Exim 4.96 through 4.98.1 could allow users (with command-line access) to escalate privileges.

Exim 4.72 and earlier allows local users to gain privileges by leveraging the ability of the exim user account to specify an alternate configuration file with a directive that contains arbitrary commands, as demonstrated by the spool_directory directive.

Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the spool directory (owned by a non-root user), an attacker can write to a /var/spool/exim4/input spool header file, in which a crafted recipient address can indirectly lead to command execution.

The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack.

Poly Plantronics Hub Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Poly Plantronics Hub. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Spokes Update Service. By creating a symbolic link, an attacker can abuse the service to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-18271.

yt-grabber-tui is a terminal user interface application for downloading videos. In versions before 1.0-rc, the application allows users to configure the path to the yt-dlp executable via the path_to_yt_dlp configuration setting. An attacker with write access to the configuration file or the filesystem location of the configured executable can replace the executable with malicious code or create a symlink to an arbitrary executable. When the application invokes yt-dlp, the malicious code is executed with the privileges of the user running yt-grabber-tui. This vulnerability has been patched in version 1.0-rc.

Measuresoft ScadaPro Server and Client (All Versions) do not properly resolve links before file access; this could allow privilege escalation..

A privilege escalation vulnerability exists in the Snapshot functionality of Parallels Desktop for Mac version 20.1.1 (build 55740). When a snapshot of a virtual machine is taken, a root service writes to a file owned by a normal user. By using a hard link, an attacker can write to an arbitrary file, potentially leading to privilege escalation.

An updater link following vulnerability in the Trend Micro Apex One agent could allow a local attacker to abuse the updater to delete an arbitrary folder, leading for a local privilege escalation on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A privilege escalation vulnerability exists in the Snapshot functionality of Parallels Desktop for Mac version 20.1.1 (build 55740). When a snapshot of a virtual machine is deleted, a root service verifies and modifies the ownership of the snapshot files. By using a symlink, an attacker can change the ownership of files owned by root to a lower-privilege user, potentially leading to privilege escalation.

cci_dir in IBM U2 UniVerse 10.0.0.9 and earlier creates hard links and unlinks files as root, which allows local users to gain privileges by deleting and overwriting arbitrary files.
