GHSA-FQF6-GXHH-2XHW uutils coreutils: cp/install/mv/ln --suffix alone does not enable backup mode (silent data loss vs GNU)

determinebackupmode in src/uucore/src/lib/features/backupcontrol.rs only checks --backup/-b and returns BackupMode::None when only --suffix is given. GNU enables backup mode when --suffix is used alone defaulting to existing/numbered, or $VERSIONCONTROL. Affects cp, install, mv, ln which share th...

GHSA-P7H3-7Q52-72W8 printenv: environment variables with invalid UTF-8 are silently skipped (evades inspection)

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...

GHSA-WV33-5PXH-R7J7 cut: -s (only-delimited) ignored when delimiter is a newline

The cut utility in uutils coreutils incorrectly handles the -s only-delimited option when a newline character is specified as the delimiter. The implementation fails to verify the onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

GHSA-6GCW-W7CP-94G9 comm: lossy UTF-8 conversion silently corrupts non-UTF-8 output

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...

GHSA-2W8R-9XJ7-69J5 mktemp: empty TMPDIR creates temp files in CWD instead of /tmp

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-2026-35348

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-2026-35339

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-2026-35340

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-2026-35358

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...

CVE-2026-35375

A logic error in the split utility of uutils coreutils causes the corruption of output filenames when provided with non-UTF-8 prefix or suffix inputs. The implementation utilizes tostringlossy when constructing chunk filenames, which automatically rewrites invalid byte sequences into the UTF-8...

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...

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...

GHSA-Q94G-3GCF-66X7 Duplicate Advisory: uutils coreutils has an Incorrect Authorization issue

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-47c7-qrm7-mqw7. This link is maintained to preserve external references. Original Description The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's...

GHSA-53GR-WMF4-8HH3 Duplicate Advisory: uutils coreutils's User Interface (UI) Misrepresents Critical Information

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xv5w-cw7x-72gj. This link is maintained to preserve external references. Original Description The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and...

GHSA-6G8R-74QP-6859 uutils coreutils has a 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 has an Incorrect Provision of Specified Functionality Issue

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...

uutils coreutils has a UNIX Symbolic Link (Symlink) Following issue

A logic error in the ln utility of uutils coreutils allows the utility to dereference a symbolic link target even when the --no-dereference or -n flag is explicitly provided. The implementation previously only honored the "no-dereference" intent if the --force overwrite mode was also enabled. Thi...
