Detailsinfo

A vulnerability was found in Uutils coreutils up to 0.7.x. It has been rated as problematic. This issue affects the function to_string_lossy of the component split Utility. The manipulation with an unknown input leads to a improper handling of unicode encoding vulnerability. Using CWE to declare the problem leads to CWE-176. The product does not properly handle when an input contains Unicode encoding. Impacted is integrity. The summary by CVE is:

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 to_string_lossy() when constructing chunk filenames, which automatically rewrites invalid byte sequences into the UTF-8 replacement character (U+FFFD). This behavior diverges from GNU split, which preserves raw pathname bytes intact. In environments utilizing non-UTF-8 encodings, this vulnerability leads to the creation of files with incorrect names, potentially causing filename collisions, broken automation, or the misdirection of output data.

The weakness was released by Zellic. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-35375 since 04/02/2026.
