|---|---|---|---|---|---|---|---|---|
| CVE-2026-35368 | Hig | 0.51 | 7.8 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35352 | Hig | 0.46 | 7.0 | 0.00 | Apr 22, 2026 | A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO… | ||
| CVE-2026-35341 | Hig | 0.46 | 7.1 | 0.00 | Apr 22, 2026 | A vulnerability in uutils coreutils mkfifo allows for the unauthorized modification of permissions on existing files. When mkfifo fails to create a FIFO because a file already exists at the target path, it fails to terminate the operation for that path and continues to execute a… | ||
| CVE-2026-35350 | Med | 0.43 | 6.6 | 0.00 | Apr 22, 2026 | The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned… | ||
| CVE-2026-35374 | Med | 0.41 | 6.3 | 0.00 | Apr 22, 2026 | A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the split utility of uutils coreutils. The program attempts to prevent data loss by checking for identity between input and output files using their file paths before initiating the split operation. However, the… | ||
| CVE-2026-35364 | Med | 0.41 | 6.3 | 0.00 | Apr 22, 2026 | A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mv utility of uutils coreutils during cross-device operations. The utility removes the destination path before recreating it through a copy operation. A local attacker with write access to the destination… | ||
| CVE-2026-35360 | Med | 0.41 | 6.3 | 0.00 | Apr 22, 2026 | 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 O_TRUNC. An attacker can exploit… | ||
| CVE-2026-35338 | Hig | 0.40 | 7.3 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35349 | Med | 0.37 | 6.7 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35365 | Med | 0.36 | 6.6 | 0.00 | Apr 22, 2026 | 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.… | ||
| CVE-2026-35363 | Med | 0.36 | 5.6 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35348 | Med | 0.36 | 5.5 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35356 | Med | 0.34 | 6.3 | 0.00 | Apr 22, 2026 | A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the install utility of uutils coreutils when using the -D flag. The command creates parent directories and subsequently performs a second path resolution to create the target file, neither of which is anchored to a… | ||
| CVE-2026-35355 | Med | 0.34 | 6.3 | 0.00 | Apr 22, 2026 | 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 O_EXCL flag. A local… | ||
| CVE-2026-35345 | Med | 0.34 | 5.3 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35359 | Med | 0.31 | 4.7 | 0.00 | Apr 22, 2026 | 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 O_NOFOLLOW flag.… | ||
| CVE-2026-35357 | Med | 0.31 | 4.7 | 0.00 | Apr 22, 2026 | The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions (e.g., 0644) before being restricted to their final mode (e.g., 0600) later in the process. A local attacker can… | ||
| CVE-2026-35354 | Med | 0.31 | 4.7 | 0.00 | Apr 22, 2026 | A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute (xattr) preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A… | ||
| CVE-2026-35380 | Med | 0.29 | 5.5 | 0.00 | Apr 22, 2026 | 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… | ||
| CVE-2026-35370 | Med | 0.29 | 4.4 | 0.00 | Apr 22, 2026 | 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… |
