CVE-2026-35359: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

CVE-2026-35355: Time-of-check Time-of-use (TOCTOU) Race Condition

The install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the OEXCL flag. A local attacker can exploit t...

CVE-2026-35353: Time-of-check Time-of-use (TOCTOU) Race Condition

The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions typically 0755 before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces ...

CVE-2026-35349: Improper Link Resolution Before File Access

A vulnerability in the rm utility of uutils coreutils allows a bypass of the --preserve-root protection. The implementation uses a path-string check rather than comparing device and inode numbers to identify the root directory. An attacker or accidental user can bypass this safeguard by using a...

CVE-2026-35348: Uncaught Exception

The sort utility in uutils coreutils is vulnerable to a process panic when using the --files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and utilizes expect, causing an immediate crash when encountering valid but non-UTF-8 paths. This diverg...

CVE-2026-35345: Time-of-check Time-of-use (TOCTOU) Race Condition

A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting the...

CVE-2026-35342: Insecure Temporary File

The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the...

CVE-2026-35338: Improper Limitation of a Pathname to a Restricted Directory

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbol...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. There is a security vulnerability in uutils coreutils. This vulnerability arises from the fact that the mktemp utility fails to properly handle the empty TMPDIR environment variable. Unlike GNU mktemp,...

PT-2026-34474

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description A flaw in the chmod utility allows users to bypass the --preserve-root safety mechanism. The implementation validates if the target path is literally '/', but fails to canonicalize t...

PT-2026-34477

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description A flaw in the mkfifo utility allows for the unauthorized modification of permissions on existing files. When the utility fails to create a FIFO because a file already exists at the...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. There is a security vulnerability in uutils coreutils, which stems from a race condition during the chcon recursive operation between checking time and execution time. This condition may allow local...

uutils coreutils path traversal vulnerability

uutils coreutils is a cross-platform core command-line toolset developed by Uutils. uutils coreutils has a path traversal vulnerability. This vulnerability arises from bypassing the security mechanism that protects the current directory, potentially leading to unexpected or malicious execution of...
