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/1808095 Title: uniq is not checking and handling all file types Status in coreutils package in Ubuntu: New Bug description: Hi, The utility uniq allows all types of files as input. Allowing block devices or character devices as input can lead to unwanted behavior such as the utility executes indefinitely when device '/dev/urandom' is passed as an input. Please refer this for more information regarding this issue (https://github.com/pkmoore/rrapper/blob/master/anomalies/weird_filetypes.md). I've included a patch which checks and handles character devices and block devices when passed as input. I've tested the patched version and it doesn't seem to break any tests but I'm always glad to further work on it. Please get back to me with any feedback or for more information.
