The _rl_tropen function in util.c in GNU readline before 6.3 patch 3 allows local users to create or overwrite arbitrary files via a symlink attack on a /var/tmp/rltrace.[PID] file.
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.
