uutils coreutils cut Local Logic Error and Data Integrity Issue in Output Filtering

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.

uutils coreutils 安全漏洞

uutils coreutils是Uutils开源的一个跨平台核心命令行工具集。 uutils coreutils存在安全漏洞，该漏洞源于cut逻辑错误，在同时使用-z和-d选项时忽略-s标志，可能导致依赖cut -s过滤无分隔数据的自动化管道出现数据完整性风险。
