Description
A vulnerability in the uutils coreutils mkfifo command allows unauthorized modification of file permissions when mkfifo fails to create a FIFO due to an existing file. Instead of terminating, mkfifo proceeds to reset the existing file's permissions to default, potentially exposing sensitive files such as SSH private keys. This affects multiple versions of rust-coreutils prior to 0.10.0-1ubuntu1. A fix is available in version 0.10.0-1ubuntu1.
