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 fts_accpath) rather than binding the traversal...
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...
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...
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:]...
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...
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...
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 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...
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...
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 nohup utility in uutils coreutils creates its default output file, nohup.out, without specifying explicit restricted permissions. This causes the file to inherit umask-based permissions, typically resulting in a world-readable file (0644). In multi-user...
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...
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...
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...
