CVE-2026-35356 Details
Description
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 directory file descriptor. An attacker with concurrent write access can replace a path component with a symbolic link between these operations, redirecting the privileged write to an arbitrary file system location.
A Time-of-Check to Time-of-Use (TOCTOU) vulnerability has been identified in the install utility of uutils coreutils, specifically in version 0.7.0. The issue arises when the -D flag is used, as the command creates parent directories and then performs a second path resolution to create the target file. Neither of these operations is anchored to a directory file descriptor, allowing an attacker with concurrent write access to replace a path component with a symbolic link. This could redirect the privileged write to an arbitrary location in the file system.
Users can update to uutils coreutils version 0.7.0 or later, where this vulnerability has been fixed.
