AI-suggested
A patch is available in uutils coreutils version 0.8.0 that corrects the character class definitions in the tr utility. Users should upgrade to version 0.8.0 or later to resolve this issue. No additional mitigation steps are required once the update is applied.
Description
A logic error in the tr utility of uutils coreutils incorrectly defines the [:graph:] and [:print:] character classes by including the ASCII space in [:graph:] and excluding it from [:print:]. This reverses the expected POSIX and GNU coreutils behavior, potentially causing unintended data modification or loss in automated scripts or data-cleaning pipelines that rely on these character classes.
