Detailsinfo

A vulnerability, which was classified as critical, has been found in Uutils coreutils up to 0.6.x. Affected by this issue is an unknown part of the component Mv Utility. The manipulation with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 resource exhaustion (disk space or time) if symlinks point to large external directories, unexpected duplication of sensitive data into unintended locations, or infinite recursion and repeated copying in the presence of symlink loops.

The weakness was disclosed by Zellic. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-35365 since 04/02/2026. The exploitation is known to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available.

Upgrading to version 0.7.0 eliminates this vulnerability.
