Detailsinfo

A vulnerability was found in Uutils coreutils up to 0.7.x and classified as problematic. Affected by this issue is an unknown function. The manipulation with an unknown input leads to a incorrect provision of specified functionality vulnerability. Using CWE to declare the problem leads to CWE-684. The code does not function according to its published specifications, potentially leading to incorrect usage. Impacted is integrity. CVE summarizes:

A logic error in the cut utility of uutils coreutils causes the utility to ignore the -s (only-delimited) flag when using the -z (null-terminated) and -d '' (empty delimiter) options together. The implementation incorrectly routes this specific combination through a specialized newline-delimiter code path that fails to check the record suppression status. Consequently, uutils cut emits the entire record plus a NUL byte instead of suppressing it. This divergence from GNU coreutils behavior creates a data integrity risk for automated pipelines that rely on cut -s to filter out undelimited data.

The weakness was presented by Zellic. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-35381 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.
