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,...

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-2026-35376: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the chcon utility of uutils coreutils during recursive operations. The implementation resolves recursive targets using a fresh path lookup via ftsaccpath rather than binding the traversal and label application to the specific directory...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line toolset developed by Uutils. There is a security vulnerability in uutils coreutils, which stems from an information leakage race condition. This vulnerability could allow local attackers to open files before permission restrictions are...

CVE-2026-35379: Incorrect Provision of Specified Functionality

A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the :graph: and :print: character classes. The implementation mistakenly includes the ASCII space character 0x20 in the :graph: class and excludes it from the :print: class, effectively reversing the...

Linux Distros Unpatched Vulnerability : CVE-2026-35342

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Linux Distros Unpatched Vulnerability : CVE-2026-35377

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A logic error in the env utility of uutils coreutils causes a failure to correctly parse command-line arguments when utilizing the -S split-string option. In GN...

Linux Distros Unpatched Vulnerability : CVE-2026-35340

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations. The fina...

CVE-2026-35367: Incorrect Permission Assignment for Critical Resource

The nohup utility in uutils coreutils creates its default output file, nohup.out, without specifying explicit restricted permissions. This causes the file to inherit umask-based permissions, typically resulting in a world-readable file 0644. In multi-user environments, this allows any user on the...

CVE-2026-35378: Incorrect Short Circuit Evaluation

A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR | and AND & operation...

Linux Distros Unpatched Vulnerability : CVE-2026-35379

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the :graph: and :print: character classes. The implementation...

Linux Distros Unpatched Vulnerability : CVE-2026-35351

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a...

Linux Distros Unpatched Vulnerability : CVE-2026-35363

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A vulnerability in the rm utility of uutils coreutils allows the bypass of safeguard mechanisms intended to protect the current directory. While the utility...

CVE-2026-35381: Incorrect Provision of Specified Functionality

A logic error in the cut utility of uutils coreutils causes the utility to ignore the -s only-delimited flag when using the -z null-terminated and -d '' empty delimiter options together. The implementation incorrectly routes this specific combination through a specialized newline-delimiter code...

CVE-2026-35346: Improper Handling of Unicode Encoding

The comm utility in uutils coreutils silently corrupts data by performing lossy UTF-8 conversion on all output lines. The implementation uses String::fromutf8lossy, which replaces invalid UTF-8 byte sequences with the Unicode replacement character U+FFFD. This behavior differs from GNU comm, whic...

CVE-2026-35340: Incorrect Check of Function Return Value

A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations. The final exit code is determined only by the last file processed. If the last operation succeeds, the command returns 0 even if earlier ownershi...

CVE-2026-35363: Improper Limitation of a Pathname to a Restricted Directory

A vulnerability in the rm utility of uutils coreutils allows the bypass of safeguard mechanisms intended to protect the current directory. While the utility correctly refuses to delete . or .., it fails to recognize equivalent paths with trailing slashes, such as ./ or .///. An accidental or...
