Subject: [PATCH 0/2] Fix chsh when called as root
Date: Sat, 21 Sep 2019 20:50:19 +0200
Message-ID: <20190921185021.10568-1-quinq@fifth.space> (raw)


Because chsh was using getpwuid/getpwnam, there was an issue with
subsequent call to readline with tilde expansion which would also call
the same function and overwrite the getpwuid/getpwnam internal storage
struct passwd, replacing passed username results.
