uutils coreutils cut Local Logic Error and Data Integrity Issue in Delimiter Parsing

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.

输入验证不恰当

uutils coreutils 输入验证错误漏洞

uutils coreutils是Uutils开源的一个跨平台核心命令行工具集。 uutils coreutils存在输入验证错误漏洞，该漏洞源于cut逻辑错误，将字面两字节字符串错误解释为空分隔符，可能导致在包含这些字符的字符串处理自动化脚本和数据管道中出现静默数据损坏或逻辑错误。
