Thank you for opening this bug and helping make Ubuntu/GNU Coreutils better. I have sent email to coreut...@gnu.org asking about this, and a few other bugs relating to the same basic issue, and am waiting on feedback from upstream:
Hello, We have had some bugs reported recently at our BTS: https://bugs.launchpad.net/bugs/1807295 https://bugs.launchpad.net/bugs/1807797 https://bugs.launchpad.net/bugs/1808092 https://bugs.launchpad.net/bugs/1808095 They deal with sort, split, fmt, and uniq, respectively, and provide tentative patches. I would like to re-direct the reporters to upstream (i.e., you folks), but I feel it would be nice to do the redirect with a small blurb of what upstream thinks about that. Thank you, ..C.. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1808092 Title: Checking and handling various filetypes in fmt Status in coreutils package in Ubuntu: New Bug description: fmt doesn't check filetypes of the input arguments passed to it, it just opens the file and reads from it without checking its st_mode. It only throws an error if the file doesn't exist and can't handle the following filetypes - S_IFCHR, S_IFBLK and S_IFBLK. Passing a file from any of these types will possibly hang or crash the application. For more reference, please visit the below link- (https://github.com/pkmoore/rrapper/blob/master/anomalies/weird_filetypes.md) I have attached a patch that checks for the above mentioned filetypes and handles them accordingly. Please let me know if you have any questions or suggestions regarding this, will be happy to answer them.
