bash-doc 3.2 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/cb#####.? temporary file, related to the (1) aliasconv.sh, (2) aliasconv.bash, and (3) cshtobash 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.
