CVE-2026-35380

Full vulnerability record from the local CVENow database.

Description

A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' (two single quotes) as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d (delimiter) and --output-delimiter options. This vulnerability can lead to silent data corruption or logic errors in automated scripts and data pipelines that process strings containing these characters, as the utility may unintentionally split or join data on NUL bytes rather than the intended literal characters.

La implementación mapea erróneamente esta cadena al carácter NUL tanto para las opciones -d (delimitador) como --output-delimiter. Esta vulnerabilidad puede llevar a una corrupción silenciosa de datos o a errores lógicos en scripts automatizados y pipelines de datos que procesan cadenas que contienen estos caracteres, ya que la utilidad puede dividir o unir datos involuntariamente en bytes NUL en lugar de los caracteres literales previstos."
