Debian advisory: exmh

Author: JT Smith

"Former versions of the exmh program used /tmp for storing temporary
files. No checks were made to ensure that nobody placed a symlink
with the same name in /tmp in the meantime and thus was vulnerable to
a symlink attack. This could lead to a malicious local user being
able to overwrite any file writable by the user executing exmh." Full details at LWN.net.
