Stack-based buffer overflow in lib/sh/eaccess.c in GNU Bash before 4.2 patch 33 might allow local users to bypass intended restricted shell access via a long filename in /dev/fd, which is not properly handled when expanding the /dev/fd prefix.

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.
