Package        : exmh
Vulnerability  : local insecure tempfile creation
Debian-specific: no
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. Upstream developers have reported and fixed this. The exmh program now use /tmp/login now unless TMPDIR or EXMHTMPDIR is set.

We recommend you upgrade your exmh packages immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
You may use an automated update by adding the resources from the footer to the proper configuration.
