uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. uutils coreutils has a vulnerability related to input validation errors. This vulnerability stems from a cut logic error, which incorrectly interprets two-byte literal strings as empty delimiters. This...

PT-2026-34516

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description A logic error in the cut utility causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly map...

uutils coreutils security vulnerabilities

uutils coreutils is a cross-platform core command-line tool set developed by Uutils Open Source. There is a security vulnerability in uutils coreutils. This vulnerability arises from the cp utility’s failure to properly handle the setuid and setgid bits when ownership retention fails. When copyin...

uutils coreutils post-linkage vulnerability

uutils coreutils is a cross-platform core command-line toolset developed by Uutils Open Source. uutils coreutils has a post-installation link vulnerability. This vulnerability stems from the rm utility allowing bypass of the --preserve-root protection. Instead of using device and inode numbers fo...

PT-2026-34486

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description The cp utility fails to properly handle setuid and setgid bits when ownership preservation fails. When using the '-p' preserve flag, the utility applies the source mode bits even if...

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 race conditions during operations across devices. This vulnerability could allow local attackers to redirect writes through symbolic links,...

CVE-2026-35339: Incorrect Check of Function Return Value

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-2026-35381: 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-2026-35378: 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...

CVE-2026-35375: Improper Handling of Unicode Encoding

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-2026-35368: Untrusted Search Path

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...

CVE-2026-35365: Improper Link Resolution Before File Access

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-2026-35360: Time-of-check Time-of-use (TOCTOU) Race Condition

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 ...

CVE-2026-35357: Time-of-check Time-of-use (TOCTOU) Race Condition

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 race to open the file...

CVE-2026-35350: Improper Preservation of Permissions

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 copy retaining origin...

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-2026-35380: Improper Input Validation

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...

CVE-2026-35377: Improper Input Validation

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...

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...
