CVE-2026-35365

The mv utility in uutils coreutils improperly handles directory trees containing symbolic links during moves across filesystem boundaries. Instead of preserving symlinks, the implementation expands them, copying the linked targets as real files or directories at the destination. This can lead to...

CVE-2026-35349

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...

UBUNTU-CVE-2026-35366

The printenv utility in uutils coreutils fails to display environment variables containing invalid UTF-8 byte sequences. While POSIX permits arbitrary bytes in environment strings, the uutils implementation silently skips these entries rather than printing the raw bytes. This vulnerability allows...

CVE-2026-35342

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...

UBUNTU-CVE-2026-35369

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal SIGTERM to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massi...

CVE-2026-35339

The recursive mode -R of the chmod utility in uutils coreutils incorrectly handles exit codes when processing multiple files. The final return value is determined solely by the success or failure of the last file processed. This allows the command to return an exit code of 0 success even if error...

CVE-2026-35358

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

UBUNTU-CVE-2026-35342

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...

UBUNTU-CVE-2026-35360

The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create, which internally uses OTRUNC. An attacker can exploit this window to create ...

UBUNTU-CVE-2026-35358

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

UBUNTU-CVE-2026-35365

The mv utility in uutils coreutils improperly handles directory trees containing symbolic links during moves across filesystem boundaries. Instead of preserving symlinks, the implementation expands them, copying the linked targets as real files or directories at the destination. This can lead to...

UBUNTU-CVE-2026-35378

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...

CVE-2026-35363

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...

UBUNTU-CVE-2026-35373

A logic error in the ln utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms e.g., ln SOURCE... DIRECTORY. While GNU ln treats filenames as raw bytes and creates the links correctly, the uutils implementation...

UBUNTU-CVE-2026-35371

The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for the effective user. This results in misleadi...

CVE-2026-35369

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal SIGTERM to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massi...

UBUNTU-CVE-2026-35353

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-2026-35381

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-2026-35381 uutils coreutils cut Local Logic Error and Data Integrity Issue in Output Filtering

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-2026-35381

CVE-2026-35381 describes a logic error in the cut utility of the uutils coreutils project. When using -z (null-terminated) and -d '' (empty delimiter) together with -s (only-delimited), the code path incorrectly routes the case to a newline-delimiter handler that does not check record suppression...
