i2myspell in myspell 3.1 allows local users to overwrite arbitrary files via a symlink attack on (1) /tmp/i2my#####.1 and (2) /tmp/i2my#####.2 temporary files.
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.
