Detailsinfo

A vulnerability was found in Uutils coreutils up to 0.7.x and classified as problematic. Affected by this issue is the function cut_fields_newline_char_delim of the component cut Utility. The manipulation with an unknown input leads to a control flow vulnerability. Using CWE to declare the problem leads to CWE-670. The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. Impacted is integrity. CVE summarizes:

The cut utility in uutils coreutils incorrectly handles the -s (only-delimited) option when a newline character is specified as the delimiter. The implementation fails to verify the only_delimited flag in the cut_fields_newline_char_delim function, causing the utility to print non-delimited lines that should have been suppressed. This can lead to unexpected data being passed to downstream scripts that rely on strict output filtering.

The weakness was released by Zellic. The advisory is available at github.com. This vulnerability is handled as CVE-2026-35343 since 04/02/2026. The exploitation is known to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit.

Upgrading to version 0.8.0 eliminates this vulnerability.
