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...

UBUNTU-CVE-2026-35370

The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes...

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-2026-35380

A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d delimiter and --output-delimiter options. Th...

UBUNTU-CVE-2026-35346

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...

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-2026-35358

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-2026-35381

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...

UBUNTU-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-2026-35368

A vulnerability exists in the chroot utility of uutils coreutils when using the --userspec option. The utility resolves the user specification via getpwnam after entering the chroot but before dropping root privileges. On glibc-based systems, this can trigger the Name Service Switch NSS to load...

UBUNTU-CVE-2026-35377

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 GNU env, backslashes within single quotes are treated literally with the exceptions of \ and '. However, the uutils implementation...

UBUNTU-CVE-2026-35379

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...

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-2026-35379 uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling

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...
