uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling

A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the [:graph:] and [:print:] character classes. The implementation mistakenly includes the ASCII space character (0x20) in the [:graph:] class and excludes it from the [:print:] class, effectively reversing the standard behavior established by POSIX and GNU coreutils. This vulnerability leads to unintended data modification or loss when the utility is used in automated scripts or data-cleaning pipelines that rely on standard character class semantics. For example, a command executed to delete all graphical characters while intending to preserve whitespace will incorrectly delete all ASCII spaces, potentially resulting in data corruption or logic failures in downstream processing.

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tr逻辑错误，错误定义了图形字符类和可打印字符类，可能导致在依赖标准字符类语义的自动化脚本或数据清理管道中出现意外的数据修改或丢失。
