Detailsinfo

A vulnerability, which was classified as problematic, has been found in Uutils coreutils up to 0.5.x. This issue affects the function safe_traversal. The manipulation with an unknown input leads to a toctou vulnerability. Using CWE to declare the problem leads to CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize these protections, leaving directory traversal operations vulnerable to symlink race conditions.

The weakness was published by Zellic. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-35362 since 04/02/2026. The exploitation is known to be difficult. An attack has to be approached locally. Technical details are known, but no exploit is available.
