alsa-utils 1.0.19 and later versions allows local users to overwrite arbitrary files via a symlink attack via the /usr/bin/alsa-info and /usr/bin/alsa-info.sh scripts.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
